Waa muhiim in la fahmo tan intaanan sii fogaanin. Sida aan u booqano saloon si aan wax uga beddelno muuqaalkeenna oo aan u noqonno kuwo casri ah. Sidoo kale, waxaad u baahan tahay inaad qaabayso awoodaha qalabka kombayutaradaada gaarka ah. Waa inaad ka warqabtaa Nidaamyada^(Systems) Hawlgelinta ee ugu wanaagsan ee maanta la isticmaalo. Laakin, waa inaad sidoo kale ku dadaashaa hababka qalliinka ee ugu xun si aad naftaada uga badbaadiso kombiyuutarrada gaabis ah ama dhaawacan. Waxaan kuugu soo qaadaneynaa liiska nidaamyada hawlgalka ee ugu guul daraystay ee maqaalkan.

10ka Nidaam ee ugu Wanaagsan^{(Top 10 Worst Operating Systems)}

Guud ahaan loo soo gaabiyo OS , Operating System waxa ay gacanta ku haysaa xogta nidaamka waxa ayna u shaqeysaa sidii isku xidhka u dhexeeya hardware-ka iyo software-ka kombiyuutarka. Si fudud^(Simply) loo dhigo, waxay u shaqeysaa sidii isgaarsiineed qofka ku shaqeeya PC iyo mashiinka laftiisa. Nidaamyada^(Systems) hawlgalka waxaa loo kala saari karaa:

• Nidaamyada hawlgalka kumbuyuutarka ee ujeeddada guud
• Nidaamyada hawlgalka mobilada ee waqtiga-dhabta ah.

Aynu hadda ka wada hadalno 10ka Nidaam^(Systems) ee Hawleed ee ugu xumaa abid si gaar gaar ah. 

1. MS-DOS 4.0

Badeeco iska leh Microsoft oo la sameeyay 1986^{(developed in 1986)} , ayaa lagu sii daayay suuqa 1988. Marka la barbardhigo noocyadii hore, waxaa loo calaamadeeyay inay tahay ukunta qudhuntay ee dambiisha Microsoft sababaha hoos ku taxan:

• Waxay joojin lahayd shaqada dhexda, meelna ka baxsan.
• Waxa ay kari wayday hawlo badan; marka, waxa ay wada shaqaynaysaa hal barnaamij markiiba 
• Awood la'aanteeda^{(inability to multitask)} hawlo badan awgeed , waxay ahayd mid aan ku habboonayn codsiyada goobta shaqada
• OS-kani wuxuu ahaa mid aad ugu tiirsan isticmaale^{(highly user-dependent)} . Sidaa darteed, lama isticmaali karo haddii isticmaaluhu illoobaan amarradiisa. 
• Isticmaalayaasha cusub, way ku adkeyd in la xasuusto dhammaan amarrada. Tani waxay ka dhigtay inay ka guuraan software-kan. 
• Waxa ay dhibaato kala kullantay gelitaanka RAM kasta oo leh in ka badan 640 MB oo meel wax lagu kaydiyo.
• Ma ay aqbalin Codsiga Joojinta tooska ah (IRQ)^{(Interrupt Request (IRQ) command)} . Sidaas awgeed, isticmaaluhu ma wadi karo barnaamij kasta oo cusub marka uu barnaamijku mar horeba hakad ku jiro.

2. Daaqadaha ME^{(2. Windows ME)}

Windows ME ama daabacaadda Millennium^{(Millennium Edition)} -ka ee Windows waxay ahayd software iska leh Microsoft oo ^(Microsoft) la bilaabay Sebtembar 2000^{(launched in September 2000)} . Waxay lahayd cilladaha soo socda:

• Iyadoo lagu fuulay cayayaan, waxay noqotay nidaam aad u deggan. 
• Astaamaha ay ka midka yihiin Soo celinta Nidaamka & Rakibaadda Barnaamijku waxay ahaayeen masiibo dhammaystiran^{(System Restore & Program Installation were a complete disaster)} sababtoo ah waxay dib ugu rakibeen fayrasyadii mar hore la tirtiray kombuyutarka.
• Tani waxay ka dhigtay mid aad u gaabis ah, aan ammaan lahayn, iyo nidaam aan degganayn^{(slow, insecure, and unstable system)} .
• Qiyaasaha nidaamka^(System) aaladaha qaar ma aysan taageerin qalabka horay loo rakibay.
• Marar badan, dhaqaaqa jiirka ka dib ku laabashada shaqada ka dib nasasho yar yar, taasoo keentay burburka Windows ME .
• Sababta kale waxay ahayd in isticmaalkeedu uu ku koobnaa^{( usage was limited)} dadka isticmaala guriga oo keliya.
• OS-kan lagama helin suuqa furan. 
• Cusbooneysii la'aanta amnigu waxay ahayd dhibaato kale oo weyn oo software-kan.
• Isku dayga in uu u shaqeeyo labadaba, 16-bit & 32-bit OS waxay keeneen qalalaase badan shaqadiisa halkii ay ka hagaajin lahaayeen.
• Sababta ugu weyn ee guul-darradu waxay ahayd ka noqoshada taageerada Microsoft^{(withdrawal of support by Microsoft)} lafteeda. 
• Daah- furka Windows XP^{(Windows XP)} , kaliya hal sano gudaheed markii la sii daayay software-kan, wuxuu noqday dharbaaxo dhimasho leh.

3. Windows Vista

Windows Vista ayaa la sii daayay bishii Noofambar ee 2006^{(month of November in 2006)} , ka dib markii la sii daayay Windows XP , oo ka horreeyay oo awood leh. Waxaa cad in ay aad ugu dadaashay in ay magac ku yeelato suuqa. Nasiib darro, waxa ay dhisi kari wayday sumcadeeda waxaana loo calaamadeeyay in ay ka mid tahay tobanka nidaam ee ugu xumaa ee abid soo mara. Waa tan sababta:

• Software-kani waxa uu u nuglaaday barar^(bloating) yacni waxa uu hoos u dhigayaa barnaamijyada. 
• Waxa kale oo ay qabsatay meel weyn oo xusuusta ah iyadoo ay ugu wacan tahay barnaamijyo badan oo horay loo sii rakibay iyo ku-darka astaamo cusub oo aan la rabin oo lagu sameeyay barnaamijyadii jiray. Tan waxaa loo yaqaana gurguurta software.
• Software-ka gurguurta ee^{(software creeping)} noocan oo kale ah ayaa ka dhigay jahawareer iyo mararka qaarkood, adag in la isticmaalo nidaamkan qalliinka ah.  
• Iswaafajin liidata^{(poor compatibility)} ayaa udhaxaysay qalabka iyo software-ka. Tusaale ahaan, Windows 7 kuma habboona Windows Vista . Marka, sida caadiga ah, labadaba isku mar lama isticmaali karo, isla kombuyutarka, sababtoo ah shuruudaha qalabka kala duwan. Sidaa darteed, Windows Vista wuxuu u baahan yahay kombiyuutarada Vista ku habboon oo keliya.
• Sababo ammaan dartood, waxay ogolaatay kaliya rakibidda ^{(only allowed the installation of)} darawallada saxeexan^{(signed drivers)} . Tani waxay ka dhigan tahay in horumariyaha software uu u baahan doono inuu ka helo shahaadada Authenticode ee ^{(Authenticode)}Microsoft . Shahaadadani waxay ahayd mid aad qaali u ah oo aanay gaadhi karin kuwa yaryar, kuwa aan summada lahayn.
• Qiimayntu^(Pricing) waxay ahayd arin kale oo ku saabsan software-kan maadaama ay dadka badankiis aad ugu kharash garaysay.
• OS-kani ma ogola barnaamijyada qaarkood sida Xidhmada Android-^{(Android Package Kit)} ka ee rakibaadda abka mobaylka, ciyaaraha mobaylada, injineernimada Aero , noocyada filimada sameeyaha ee ^(Aero)Windows , iwm.
• Suuqgeynta liidata^{(Poor marketing)} ee nidaamkan ku shaqeeya ayaa noqotay sabab kale oo keentay heerkiisa liita.

4. Windows 8/8.1

Iyadoo fikradda ah in la soo saaro isbeddello ballaaran oo is-dhexgalka isticmaalaha, software-kan waxaa la bilaabay sanadka 2012^{(launched in the year 2012)} . Microsoft waxay xaqiiqsatay in dadku aanay hadda ka shaqayn hal qalab oo ah kombayutarka gaarka ah; halkii, waxay isticmaalayeen qalab kala duwan sida laptops, tablets, phones, iwm. Sidaa darteed, Windows 8 waxaa loo soo bandhigay si ay u daboolaan shuruudaha qalabka badan^{(Windows 8 was introduced to cater to the requirements of multiple devices)} . Way ku guul-darraysatay inay gaadho ujeeddadii laga lahaa, waayo:

• Joojinta badhanka ^{(discontinuation of the)} bilawga^{(start button)} waxay ahayd sifo jahawareer leh oo ka mid ah noocaan.
• Kumay habboonayn baahiyaha kombayuutarka guriga maadaama isticmaalayaashu ay sii jah wareersan yihiin oo ay ka niyad jabeen si ka fudud.
• Waxay curyaamisay bootinta^{(disabled booting)} ie hannaankii loo bilaabay kombuyutarka ama desktop-ka. Taa baddalkeeda, waxay awood u siisay bootinta shaashadda bilowga, taasoo ka dhigeysa isticmaalayaasha jahawareer, haddana mar kale.
• Ugu dambeyntii, Microsoft waxay ku qasbanaatay inay soo celiso badhanka Start^{(Microsoft had to restore the Start button)} ee miiska si ay uga fogaato dhammaan buuqa aan loo yeerin.
• Inta badan codsiyada ku jira OS-kan ayaa awoodi waayay in ay ka shaqeeyaan iskutallaabta^{(unable to work cross-platform)} oo waxay ku shaqaynayeen Windows 8 oo keliya.
• Mid ka mid ah waxay ahayd inuu raadiyo astaanta raadinta^{(search for the search icon)} , si loo bilaabo raadinta kasta oo ku jirta kumbuyuutarkaaga.
• Sifadan waxa si fudud loogu dhejin karayey miiska miiska, dhibaatadanna waa laga fogaan karay, gebi ahaanba.
• Windows 8 wuxuu u baahday tababbarka^{(required training)} shaqaalaha shirkadda si ay u isticmaalaan software-kan urur. Tani waxay keentay ma aha oo kaliya kharashka tababarka ee aan la rabin, laakiin sidoo kale, luminta wax soo saarka shaqaalaha. Waxay qaadatay waqti badan, dadaal, iyo lacag si ay u baraan isticmaalayaasha aan farsamada ahayn software-kan, taasoo dhalinaysa waxyeello ka badan tan u wanaagsan ururka la sheegay. 
• Dib u cusboonaysiinta nidaamkan waxa ku lug lahaa isbeddelka darawallada^{(change of drivers)} ee aaladaha durugsan ee ku xidhan kombiyuutarka. Sidaa darteed^(Hence) , dhammaan aaladaha sida daabacayaasha, makarafoonnada, cod-bixiyayaasha, kamaradaha, iwm. waxay u baahdeen darawallo cusub, si ay u kordhiyaan kharashka nidaamka, xitaa in ka badan.
• Si loogu yeedho ku hadaaqaha fog ee isticmaalaya Windows 8 laptop, makarafoonka fog waxa uu u baahday isbedel lagu sameeyo darawal ku haboon. Tani waxay inta badan ka dhigtay isticmaalka shirarka fogaan la'aanta^{(remote meetings unfeasible)} .
• Xaalad kala go'a maskaxda ayaa laga abuuray xafiis ka shaqeeya nidaamyada Windows 8. Waxay keeni kartaa in xogtu xumaato ama iswaafaqdo^{(data getting corrupt or inconsistent)} .
• Windows 8 waxay keentay la'aanta xog iswaydaarsi hufan oo dhex mara shaqaalaha kala duwan ee hay'ad iyo isticmaalayaasha kala duwan ee aduunka.

Marka la eego cilladaha kor ku xusan, Microsoft ayaa sii daayay Windows 8.1 bishii Oktoobar 2013^{(October 2013)} , hal sano ka dib markii la sii daayay Windows 8 . Daaqadaha 8.1 ayaa hagaajiyay cilladihii jiray isagoo ka gudbay iswaafaqla'aanta ku jirta Windows 8 oo u sahlay isticmaalayaasha inay helaan shaqo hufan. Si kastaba ha ahaatee, taas oo sidoo kale si deg deg ah looga tanaasulay doorka Windows 10^{(Windows 10)} .

5. Daaqada 1.01^{(5. Window 1.01)}

Waa isha xiran ee Microsoft , is-dhexgal isticmaale garaaf halkii uu ka ahaan lahaa DOS -software ganacsi interface interface. In kasta oo lagu dhawaaqay in la shaaciyey Noofambar 1983^{(November 1983)} , haddana ugu dambeyntii waxaa la sii daayay sidii nooc MS-DOS lagu daray bishii Noofambar 1985kii^{(released as an added version of MS-DOS in November 1985)} . Waxaa lagu daray liiska 10ka hab ee ugu xumaa ee abid soo mara sababaha soo socda awgood:

• Is - dhexgalkeeda isticmaale oo si liidata loo qaabeeyey^{(poorly designed user interface)} ma buuxin karo baahiyaha gaarka ah ee macaamiisha.
• Burburkiisi lama filaanka ahaa ee uu ku dhex maray barnaamijka orodka ayaa muujiyay sida ay u liidato shaqada^{(poor workability)} . Tani waxay sii kordhisay dabka.
• Dib u dhaca ku yimid hirgalinta nidaamkan laba sano ayaa waxa uu sababay burburkiisa.
• Helitaanka Mac 2.1 kan aad uga sarreeya^{(superior Mac 2.1 OS)} oo ay ku jiraan  isku xidhka AppleTalk , daabacaadda ^(AppleTalk)PostScript oo leh daabacaha qoraha laysarka, iyo Nidaamka Faylka Sare^{(Hierarchical File System)} ee PC-ku-salaysan ee casriga ah ayaa ka awood roonaaday sifooyinkiisa. Sidaa awgeed, Microsoft ma dhalin kari weyday xiisaha isticmaale ee Windows 8 wakhtiga la bilaabay. 
• Muhiimaddeeda ku aaddan adeegsiga gelinta mouse-ka^{(use of mouse input)} si loo xakameeyo is-dhexgalka isticmaalaha ma ahayn mid baahsan xilligaas. Waxay ahayd wax ka baxsan fahamka isticmaalaha, sidaas darteed, ma ay heli karin taageere.
• U hoggaansanaanteeda Y2K oo^{(non-Y2K compliance)} ay weheliso qeexitaannada qalabka ^{(hardware specifications)}hoose^(lower) waxay keeneen arrimo shaqo.
• Helitaanka kheyraadkeeda xaddidan^{(limited resource availability)} waxay awoodi wayday inay dhaliso xiisaha la doonayo iyo/ama soo jiidashada isticmaalayaasha cusub ee Windows .

6. Corel Linux

Saddexda OS ee ugu waaweyn kombuyuutarrada oo kala ah Windows , Mac , iyo Linux , Linux ayaa ah midka ugu yar ee laga hadlo nidaamka hawlgalka ee il-furan ee fashilmay. Linux waxaa abuuray Debian waxaana lagu sii daayay suuqa furan bishii Noofambar 1999kii^{(released in the open market in November of 1999)} . Waxaa loo malaynayay in ugu dambeyntii la joojiyo keli-taliska Microsoft laakiin si xun ayay u fashilantay sababtoo ah:

• Siideynta soo daahday^{(late release)} iyo helitaanka hadda jira ee nidaamyada kale ee hawlgalka sida Microsoft Windows 98, Windows 2000 , iyo Apple Mac OS 9 , kama aysan caawinin inay caan noqoto.
• Si ka duwan Windows iyo Mac , kuwaas oo lahaa noocyo badan oo qeexan, Corel Linux ma lahayn daabacaad caadi ah^{(had no standard edition)} . Iyada oo boqollaal daabacaad oo isticmaale-soo-saarku sameeyay oo sabbaynaya suuqa, waxay noqotay mid aad u adag in la doorto midka ugu fiican. Jahwareerkan ayaa ka diiday isticmaalayaasha cusub inay aqbalaan.
• Habka rakibaadda ee OS-kan wuxuu ahaa ^{(installation process of this OS was)} mid aad u dhib badan^{(very cumbersome)} taasoo ka dhigaysa rakibidda faylasha cusub ee isticmaalayaasha cusub marathon.
• Marar badan, rakibidda software-kan wuu guul-darraystay sababtoo ah khaladaadka software-^{(inherent software errors)} ka ee ku jira .
• Inta badan, way burburtay^(crashed) ka dib dib-u-kicinta bilawga ah ee faylasha rakibidda.
• Maamulaha faylka ee Corel Linux^{(Corel Linux)} ma uusan siinin si sahlan darawaladiisa oo waxay ku qaadatay waqti dheer inuu ku shubo faylasha. Tani waxay difficult to upload/download files online , oo dheeraad ah, taasoo ka niyad jabinaysa isticmaalayaasha cusub inay doortaan.
• Waxaa jirtay dhib ah in la helo ^{( difficulty in getting)} taageero farsamo^{(technical support)} si loo helo farsamayaqaannada kombuyuutarrada oo si fiican u yaqaan Linux , sida iyo marka loo baahdo.
• Iyadoo inta badan dadka loo isticmaalo Windows iyo Mac , waxay u baahan tahay dadaal dheeraad ah^{(required more effort)} iyo saldhig aqooneed oo ballaadhan si loo isticmaalo nidaamkan qalliinka ah. Aad bay ugu adag tahay isticmaalayaasha cusub waxayna ka celisay daba galkeeda.
• In kasta oo la sii daayay goor dambe, Corel Linux wuxuu ahaa mid garaaf ahaan ka horreeya waqtigeeda. Dad badan ayaa fahmi kari waayey ama isku xidhi waayey^{(could not understand or correlate)} , taasoo ka bixitaankeeda ka dhigtay mid sahlan.

7. Java OS

Maskaxdan ay leedahay Sun Microsystems^{(brainchild of Sun Microsystems)} waxaa la sameeyay iyadoo la kaashanayo kombuyuutarrada IBM waxaana dadweynaha loo sii daayay 1996kii^{(in 1996)} . Nasiib darro, uma aysan kicin sidii la filayey, in kasta oo taageerada baaxadda leh ay ka heleen kombiyuutarrada IBM . Sababaha ugu waaweyn ee ka masuulka ah guul-darradeeda waa kuwan hoos ku taxan:

• Waxqabadkeedu ma ahayn mid la mid ah tartamayaashiisa. Waxaa loo tixgeliyey inuu aad uga gaabinayo^{(drastically slower)} software-ka ku qoran other programming languages like C, C++, etc . 
• ^(Java)Nidaamka hawlgalka Java waxa lagu qoray Java , kaas oo ahaa mid ka mid ah luuqadaha barnaamijyada ugu adag^{(hardest programming languages)} marka la barbardhigo luuqadaha C, C++ ee fudud. Dadku had iyo jeer waxay door bidaan ikhtiyaarka fudud, taas oo keentay in isticmaalayaashu ay iska fogeeyaan Java .
• Nidaamka hawlgalka Java wuxuu cunay meel ^(space)xasuus badan^{(consumed higher memory)} marka la barbar dhigo OS-yada kale sababtoo ah waxaa loogu talagalay inay ku shaqeeyaan mashiinnada shabakada Java iyo nidaamyada ku-xidhan.
• Iyadoo ay ugu wacan tahay waxqabadkiisa gaabis ah iyo baahida xusuusta sare, qalabka loo baahan yahay wuxuu ahaa mid aad u adag. Tani waxay keentay kharashaadka qalabka oo sarreeya^{(higher hardware costs)} taasoo ka dhigaysa mid qaali ah.
• Ma aysan siin wax tas-hiilaad ah^{(no backup facility)} . Sidaa darteed, suurtogal ma ahayn in la soo celiyo xogta luntay sababtoo ah cillad hardware ama software.
• Sidoo kale, ma soo ceshan kartid xog kasta oo hore loo kaydiyay haddii ay dhacdo fayras xaasidnimo leh ama weerar malware ah, musuqmaasuqa xogta, ama tirtirka xogta shilalka ah.
• Nidaamka hawlgalka Java ma lahayn GUI wanaagsan^{(lacked a good GUI)} oo marar badan wuu barafoobay^{(froze repeatedly)} .

8. Symbian

Nidaamka hawlgalka Symbian ee ay Nokia^{( launched by Nokia)} soo saartay waxa uu soo baxay sanadkii 1997-kii^{( in the year 1997)} . Waxa loo nashqadeeyay sidii mobaylka ku shaqaynta iyo kombuyuutarada ee talefannada casriga ah. Waxay ka dhigtay joogitaankeeda oo la dareemay oo caan ka noqday inta lagu guda jiro furitaanka madal software Nokia S60 ee 2002. Laakiin nidaamku wuxuu lahaa khaladaad badan, isagoo gelinaya liiska tobanka nidaam ee ugu xun ee abid. Aan eegno dhowr:

• Nidaamkan qalliinka ah ee fashilmay waxaa si fudud u saameeyay cayayaanka iyo fayrasyada^{(easily affected by bugs and viruses)} .
• Waxay ahayd mid aad ugu nugul khaladaadka^{(highly prone to errors)} .
• browser-ka caadiga ah ee la siiyay Symbian OS aad buu u liitay marka loo eego jawaab celinta suuqa^{(poor in terms of market response)} mana uu tartami karin Apple iOS 2007 iyo Android sanadka soo socda.
• Marna ma hagaajin karto cilladaha ama ma hagaajin karto Interface^{(User Interface)} -ka isticmaaleheeda . Waxay u muuqatay interface interface ee Apple iyo Android , tartamayaasha.
• Nokia ma aysan dareemin joogitaankeeda mana aysan raadin codsiyo cusub oo ku saabsan nidaamka hawlgalka ee fashilmay si ay u horumariso raadkeeda suuqa.
• Symbian OS way ku adkeyd in la shubo boggaga internetka ee WAP^{(difficult to load WAP-enabled web pages)} . WAP ama Wireless Application Protocol waa qandaraas awood u siinaya isku xidhka degdega ah ee ka dhexeeya aaladaha wireless-ka sida mobilada iyo internetka.
• Software-kani waxa uu ahaa mid aan ku haboonayn noocyada kala duwan ee nidaamka hawlgalka Symbian , taas oo keentay in ay sii yaraanayso caannimadiisa isticmaalayaasha.

9. WAA^{(9. ITS)}

Nidaamka Waqti-wadaaga ee aan^{(Incompatible Timesharing System)} Is-qaban karin ama nidaamka qalliinka ITS wuxuu ahaa wax soo baxay 1960-meeyadii^{(product of the late 1960s)} . Waxaa lagu qoray DEC PDP-6 iyo PDP-10 luqadaha kulanka iyadoo fayl kasta lagu kaydiyay hagaha loo qoondeeyay. Nidaamkan qalliinka ee fashilmay waxa uu taageeray hal kiis, lix xaraf magac faylka tusaha kasta. Uma adkeysan karto tijaabada waqtiga, sidaas darteed, waxaa lagu qiimeeyay tobanka hab ee ugu xumaa ee abid soo mara sababaha hoos lagu tilmaamay:

• ITS uma baahnid furaha sirta ah si loo galo taas oo keentay in la wiiqo amniga nidaamka^{(weakened system security)} . Qof kastaa wuu geli karaa kulammadaada is-dhexgalka
• Isticmaalayaashu waxay sameeyeen sida ugu fiican ee cilladaha nidaamka waxayna isticmaaleen amarada shilalka si ay u burburiyaan nidaamka, iyaga oo ulajeedadoodu tahay inay keenaan buuq iyo qas.
• Qarsoodinimada isticmaalka sidoo kale waa la dhimay sababtoo ah qof kasta ayaa wax ka beddeli^{(anyone could edit)} kara faylashaada, dukumeentiyada khadka, iyo xitaa koodhka isha.
• Isticmaalka amarka loo yaqaan OS ama Out Spy^{(OS or Out Spy)} , qof kastaa wuxuu arki karaa waxa dhaqdhaqaaqyada ka dhacaya marinnada kale ee isticmaala isla shabakadda.
• Isticmaaluhu wuxuu u diri karaa fariin degdeg ah qof kasta^{(instant message to anyone)} , iyadoon loo eegin inay yaqaaniin iyo in kale.
• Fududeynta gelitaanka, leh ama la'aanteed akoon martida, waa la oggolaaday. Markaa, qof kastaa wuu u soo geli karaa sida dalxiiska oo wuxuu si firfircoon ugu biiri karaa fadhiga. Tani kaliya ma dhalin ee waxay dhiirigelisay dhaqanka Hackers-ka^{(encouraged the Hacker culture)} .
• Kor u kaca iyo caannimada UNIX^{(rise and popularity of UNIX)} , isticmaale badan, hawlo badan, iyo nidaamka qalliinka ee xasilloon ayaa caan ka helay nidaamkan, waqti. Waxa uu noqday xidhiidh ka wanaagsan oo badbaado badan oo u dhexeeya kombayutarka iyo isticmaalayaashiisa, taas oo ka dhigtay inay ka fogaadaan ITS . 

10. Lindows

Lindows Inc. sannadkii 2001^{(year 2001)} , wuxuu isku dayay inuu isku daro oo uu abuuro nooc isku dhafan oo Linux iyo Windows ah^{(hybrid version of Linux and Windows)} , isaga oo u magacaabay Lindows . Si ay u qabtaan suuqa Microsoft oo ay u jiidaan macaamiisheeda, horumariyayaasheeda ayaa la yimid fikradan cajiibka ah si ay isugu geeyaan UX ee Windows iyo awoodaha furan ee Debian Linux . Waxay ku fashilmeen isku daygoodii si xun sababo hoos ku tafatiran:

• Nidaamkani wuxuu ahaa mid aan loo baahnayn oo adag^{(unnecessarily complicated)} oo ay adagtahay in la isticmaalo celceliska isticmaalayaasha kombuyuutarka.
• Waxaa si fudud u saameeyay cayayaanka iyo fayrasyada.
• Inta badan abka kuma shaqayn^{(apps did not work)} goobtan
• Codsiyada waxay u baahdeen isticmaalka software WINE oo si ^(WINE)qosol leh^{(ridiculously slow)} ayay u shaqaynayeen.
• In kasta oo koofiyadda Cas Linux 8^{(Red Hat Linux 8)} ( RH 8 ) la sheegay inay tahay software bilaash ah, waxay lahayd kharashyo taageero oo qarsoon oo sarreeya^{(high hidden support costs)} , xitaa taageerada aasaasiga ah.
• Lindows wuxuu ahaa mid aad u qallafsan- u^{(clumsy-looking)} eg oo aan wax badan laga hadlin ama laga qorin.
• Haddii aad runtii rabto inaad ku socodsiiso codsiyada Windows Linux , way fiicantahay inaad hesho CodeWeavers 'CrossOver' Linux  codsiga beddelka ah.

Waxaa intaa dheer, iyadoo ay ugu wacan tahay ku xadgudubka xuquuqda daabacaada ee magaceeda, Lindows waxay ku qasbanaatay inay soo maro dacwado kala duwan. Microsoft waxay ahayd inay bixiso magdhow culus ka dibna, waxay go'aansatay inay ku isticmaasho magac cusub Linspire .

Top 10 Worst Operating Systems

It is impоrtant to understand this before we delve any further. Just like we visit a salon to modify our look and beсome trendy. Sіmilarly, you need to fashion the hardware capabіlities of your personal computers. You must be aware of the best Оperating Systems available for use today. But, you should alsо dwell on the worst operating systems to sаvе yourself from slow or damaged computers. We bring to you the list оf the best failed operatіng ѕystems in this artiсle.

Top 10 Worst Operating Systems

Generally abbreviated as OS, Operating System handles system data and acts as an interface between the hardware and the software of a computer. Simply put, it acts as a medium of communication for the person operating the PC and the machine itself. Operating Systems can be classified into:

• General-purpose computer operating systems
• Real-time mobile operating systems.

Let us now discuss the 10 worst Operating Systems of all time individually. 

1. MS-DOS 4.0

A proprietary product of Microsoft developed in 1986, was released in the market in 1988. Compared to the earlier versions, it was tagged to be the rotten egg of the Microsoft basket for the reasons listed below:

• It would just stop operating in the middle, out of nowhere.
• It could not multi-task; so, it would run only one program at a time 
• Due to its inability to multitask, it was unsuitable for work-station applications
• This OS was highly user-dependent. Hence, it could not be used in case the user forgot its commands. 
• For new users, it was difficult to remember all of the commands. This made them move away from this software. 
• It faced difficulty in accessing any RAM with more than 640 MB of storage space.
• It did not accept the automatic Interrupt Request (IRQ) command. Thus, a user could not run any new program while putting the program already running on hold.

2. Windows ME

Windows ME or the Millennium Edition of Windows was a proprietary software of Microsoft launched in September 2000. It had the following drawbacks:

• Being ridden with bugs, it became a highly unstable system. 
• Features like System Restore & Program Installation were a complete disaster because they re-installed the already deleted viruses on the computer.
• This made it a very slow, insecure, and unstable system.
• System parameters of some devices did not support the pre-installed hardware.
• Many a time, moving the mouse after returning to work post small breaks, resulting in Windows ME crashing.
• Another reason was that its usage was limited to home-users only.
• This OS was not available in the open market. 
• Lack of security updates was another major problem with this software.
• Trying to function as both, 16-bit & 32-bit OS brought about more chaos in its operation rather than improving it.
• The major reason for its failure was the withdrawal of support by Microsoft itself. 
• The launch of Windows XP, just within one year of the release of this software, proved to be a fatal blow.

3. Windows Vista

Windows Vista was released in the month of November in 2006, after the release of Windows XP, its powerful predecessor. It obviously had to toil hard to make a name for itself in the marketplace. Unfortunately, it could not build on its reputation and was flagged to be amongst the ten worst operating systems of all time. Here’s why:

• This software was prone to bloating i.e slowing down of programs. 
• It also occupied larger memory space due to numerous pre-installed programs and the addition of unwanted new features to the existing programs. This is known as software creep.
• Such software creeping made it confusing and at times, difficult to use this failed operating system.  
• There was poor compatibility between the hardware and the software. For example, Windows 7 is not compatible with Windows Vista. So, usually, both cannot be used simultaneously, on the same PC, due to different hardware requirements. Therefore, Windows Vista required only Vista-compatible computers.
• For security reasons, it only allowed the installation of signed drivers. This meant that a software developer would need to obtain an Authenticode certificate from Microsoft. This certification was very costly and out of reach for smaller, non-branded developers.
• Pricing was another issue with this software as it was very costly for most people.
• This OS did not allow certain programs such as Android Package Kit for installation of mobile apps, mobile games, Aero engineering, Windows movie maker versions, etc.
• Poor marketing of this operating system became another cause of its poor ranking.

4. Windows 8/8.1

With the idea of bringing out sweeping changes to the user interface, this software was launched in the year 2012. Microsoft realized that people no longer worked on a single device viz the personal computer; instead, they were using various devices like laptops, tablets, phones, etc. Therefore, Windows 8 was introduced to cater to the requirements of multiple devices. It failed to achieve its objective because:

• The discontinuation of the start button was an utterly confusing feature of this version.
• It did not fit the needs of a home computer as users kept getting more confused and frustrated than at ease.
• It disabled booting i.e. the process of starting a computer or a desktop. Instead, it enabled the booting of the start screen, leaving the users bewildered, yet again.
• Eventually, Microsoft had to restore the Start button on the desktop to avoid all of the uncalled-for commotions.
• Most of the applications in this OS were unable to work cross-platform and were functional in Windows 8 only.
• One had to search for the search icon, to initiate any search on your computer.
• This feature could have been easily placed on the desktop and this predicament could have been avoided, altogether.
• Windows 8 required training of company employees to use this software in an organization. This resulted not only in unwanted training costs but also, in the loss of employee productivity. It took more time, effort, and money to familiarize non-technical users with this software, generating more harm than good for the said organization. 
• Upgradation to this system involved a change of drivers in the peripheral devices attached to the computer. Hence, all devices like printers, microphones, speakers, cameras, etc. required new drivers, thereby increasing system costs, even more.
• To invite a remote speaker using Windows 8 laptop, the remote microphone required a change to a compatible driver. This often made the use of remote meetings unfeasible.
• A split-brain syndrome kind of situation was created in an office employing Windows 8 systems. It could lead to data getting corrupt or inconsistent.
• Windows 8 resulted in a lack of efficient exchange of information amongst different employees in an organization and various users the world over.

In view of the above drawbacks, Microsoft released Windows 8.1 in October 2013, one year after the release of Windows 8. Window 8.1 fixed the existing flaws by overcoming the inconsistencies in Windows 8 and enabled the users to get a more efficient functioning. Although, that too was quickly given up in favor of Windows 10.

5. Window 1.01

It is a Microsoft closed source, graphical user interface rather than DOS command-line interface commercial software. Though it was announced to be made public in November 1983, it was finally released as an added version of MS-DOS in November 1985. It was included in the list of 10 worst operating systems of all time due to the following reasons:

• Its poorly designed user interface could not meet the specific needs of the consumers.
• Its sudden collapse in the midst of a running program showed its poor workability. This just added fuel to the fire.
• The delay in the introduction of this system by two years further caused its downfall.
• The availability of the far superior Mac 2.1 OS which included AppleTalk networking, PostScript printing with laser writer printer, and sophisticated PC-based Hierarchical File System overpowered its features. Consequently, Microsoft could not generate much user interest in Windows 8 at the time of its launch. 
• Its emphasis on the use of mouse input to control the user interface was not widespread at the time. It was beyond user comprehension and thus, couldn’t garner a fanbase.
• Its non-Y2K compliance coupled with lower hardware specifications resulted in performance issues.
• Its limited resource availability was unable to generate the desired interest and/or impress the new Windows users.

6. Corel Linux

Of the three major OS for computers namely Windows, Mac, and Linux, Linux is the least talked about the open-source failed operating system. Linux was created by Debian and was released in the open market in November of 1999. It was touted to finally stop the monopoly of Microsoft but it failed miserably because:

• Its late release and existing availability of other operating systems like Microsoft Windows 98, Windows 2000, and Apple Mac OS 9, didn’t help it gain popularity.
• Unlike Windows and Mac, which had many definite versions, Corel Linux had no standard edition. With hundreds of user-developed editions floating in the market, it became very challenging to choose the best one. This confusion dissuaded new users from accepting it.
• The installation process of this OS was very cumbersome making the installation of new program files by new users a marathon.
• Most times, the installation of this software failed due to inherent software errors.
• More often than not, it crashed after an initial reboot of the installation files.
• Corel Linux file manager did not provide easy access to its drivers and took a long time to load files. This made it difficult to upload/download files online, further, discouraging new users from choosing it.
• There was difficulty in getting technical support in finding computer technicians well versed in Linux, as and when needed.
• With most of the people used to Windows and Mac, it required more effort and a broader knowledge base to use this failed operating system. It was quite challenging for new users and deterred them from pursuing it.
• Despite its late release, Corel Linux was graphically way ahead of its times. Many people could not understand or correlate, making a withdrawal from it an easier option.

7. Java OS

This brainchild of Sun Microsystems was developed with the assistance of IBM computers and was released to the public in 1996. Unfortunately, it did not take off as anticipated, in spite of the tremendous support from IBM computers. The main reasons responsible for its failure are listed below:

• Its performance was not at par with its competitors. It was considered to be drastically slower than the software written in other programming languages like C, C++, etc. 
• Java operating system was written in Java, which was one of the hardest programming languages in comparison to the simpler C, C++ languages. People always prefer the easier option, which resulted in users distancing themselves from Java.
• Java operating system consumed higher memory space as compared to other OS because it was designed to run on Java network machines and embedded systems.
• Due to its slow performance and high memory requirement, the hardware required was more complex. This resulted in higher hardware costs making it costlier.
• It provided no backup facility. So, it was not possible to recover data lost due to hardware or software failure.
• Similarly, you could not recover any previously stored data in the event of a malicious virus or malware attack, data corruption, or accidental data deletion.
• Java operating system lacked a good GUI and froze repeatedly.

8. Symbian

The Symbian operating system launched by Nokia came into existence in the year 1997. It was designed as a mobile operating and computing system for smartphones. It made its presence felt and gained popularity during the launch of the Nokia S60 software platform in 2002. But the system had many fallacies, placing it in the list of the ten worst operating systems of all time. Let us take a look at a few:

• This failed operating system was easily affected by bugs and viruses.
• It was highly prone to errors.
• The default browser provided with Symbian OS was very poor in terms of market response and could not stand in competition with Apple iOS in 2007 and Android in the following year.
• It could never rectify the deficiencies or improve its User Interface. It mirrored the user interface of Apple and Android, its competitors.
• Nokia did not make its presence felt or search for new applications for its failed operating system to improve its market footprint.
• The Symbian OS found it difficult to load WAP-enabled web pages. WAP or Wireless Application Protocol is a contract that enables instant connectivity between wireless devices like mobile phones and the internet.
• This software was incompatible with various versions of the Symbian operating system, resulting in further decreases in its popularity among its users.

9. ITS

The Incompatible Timesharing System or ITS operating system was a product of the late 1960s. It was written in DEC PDP-6 and PDP-10 assembly languages with each file stored in its designated directory. This failed operating system supported one mono-case, six-character file name per directory. It could not stand the test of time and was thus, ranked amongst the ten worst operating systems of all time for the reasons indicated below:

• ITS did not require a password to log in which led to weakened system security. Anyone could log into your interactive sessions.
• Users made the best of system flaws and used crash commands to crash the system, on purpose to cause nuisance and disturbance.
• Privacy of use also stood compromised because anyone could edit your files, online documents, and even the source code.
• Using a command called OS or Out Spy, anyone could see what activities were taking place in other user terminals on the same network.
• A user could send an instant message to anyone, irrespective of whether they knew them or not.
• Ease of access, with or without a guest account, was allowed. Thus, anyone could enter like a tourist and actively join a session. This not only gave rise to but also encouraged the Hacker culture.
• The rise and popularity of UNIX, a multi-user, multi-tasking, and more stable operating system gained popularity over this system, with time. It became a better and safer link between the computer and its users, making them pull away from ITS. 

10. Lindows

Lindows Inc. in the year 2001, tried to amalgamate and create a mix or hybrid version of Linux and Windows, naming it Lindows. In their bid to capture the Microsoft market and pull its customers away, its developers came up with this brilliant idea to combine the UX of Windows and the open-source capabilities of Debian Linux. They failed in their attempt miserably for reasons detailed below:

• This system was unnecessarily complicated and difficult to use by the average computer user.
• It was easily affected by bugs and viruses.
• The majority of the apps did not work on this platform.
• The applications required the use of WINE software and were ridiculously slow in operating.
• Though Red Hat Linux 8 (RH 8) was claimed to be free software, it had high hidden support costs, even for some basic support.
• Lindows was very clumsy-looking with not much to talk or write about.
• If you really want to run Windows applications on Linux, it is better to get CodeWeavers ‘CrossOver’ Linux application as an alternative.

Moreover, due to copyright infringement with its name, Lindows had to through various lawsuits. Microsoft had to pay a heavy compensation and then, decided to use it under a new name Linspire.
