Barnaamijyada, maamulayaasha nidaamka, iyo isticmaalayaasha awoodda ayaa laga yaabaa inay u baahdaan inay mar uun la shaqeeyaan doorsoomayaasha deegaanka. Qaar baa laga yaabaa inay rabaan inay tirtiraan doorsoomayaasha deegaanka; kuwa kale waxay rabaan inay beddelaan qiimaheeda, iyo wixii la mid ah. Hagahan waxa uu wadaagayaa sida loo tafatiro ama loo tirtiro doorsoomayaasha deegaanka, iyo sidoo kale sida loo dejiyo doorsoomayaasha deegaanka ee Windows:

Fur daaqadda kala beddelashada deegaanka^{(Environment Variables)}

Si aad wax badan uga beddesho maqaalkan, waxaad marka hore u baahan tahay inaad furto daaqada kala duwanaanshaha deegaanka . ^{(Environment Variables)}Hagahan ayaa sharaxaya sida loo sameeyo taas oo ku tusinaysa aasaaska ku saabsan la shaqaynta doorsoomayaasha deegaanka: Waa maxay doorsoomayaasha deegaanka ee Windows? ^{(What are environment variables in Windows?)}.

Daaqadda kala beddelashada deegaanka^{(Environment Variables)} ee Windows 10

Haddii aad rabto in aad ka boodo akhrintiisa, hal dariiqo oo isku mid ah oo ka shaqeeya dhammaan noocyada Windows waa inaad furto Run window (Win + R) , Command Prompt , ama PowerShell oo fuli amarka: rundll32.exe sysdm.cpl, EditEnvironmentVariables .

Sida loo beddelo doorsoomayaasha deegaanka ee Windows

Haddii aad rabto in aad beddesho qiimaha doorsoomayaasha deegaanka ee jira, marka hore ka dooro daaqadda Bey'ada Variables . ^{(Environment Variables)}Kadib, dhagsii ama tabo Waxka bedel^(Edit) .

Sida loo tafatiro doorsoomayaasha deegaanka ee Windows 10

Waxa lagu tusay daaqad aad wax kaga beddeli karto magaca iyo qiimaha doorsoomaha labadaba. Samee wax ka beddelka aad rabto oo tabo OK^(OK) . Kadibna, taabo OK hal mar oo kale gudaha daaqada kala duwanaanshaha deegaanka .^{(Environment Variables)}

Tafatirka doorsoome deegaan

Sida loo tafatiro doorsoomayaasha deegaanka ee Command Prompt

Waxaad samayn kartaa doorsoome deegaan cusub, ama aad wax ka beddeli kartaa qiimaha doorsoom deegaanka jira (laakiin ma aha magaciisa) sidoo kale Command Prompt . Amarka ay tahay inaad gasho waa:

• setx variable_name "qiimaha"^{(setx variable_name “value”)} haddii aad rabto inaad abuurto doorsoom deegaan isticmaale
• setx variable_name “value” /m haddii aad rabto inaad abuurto doorsoom deegaan nidaam

Tusaale ahaan, waxaanu ku setx TEST “C:\digitalcitizen” waxaana aanu samaynay doorsoome isticmaale oo lagu magacaabo TEST oo qiimihiisu yahay C:\digitalcitizen.

Sida loo dejiyo doorsoomayaasha deegaanka iyadoo la isticmaalayo Command Prompt

Haddii aan rabno inaan bedelno qiimaha doorsoomayaasha deegaanka, waxaan ku socodsiin karnaa isla amarka setx-ka^(setx) laakiin qeex qiime cusub doorsoomiyaha. Tusaale ahaan, fulinta setx TEST “C:\DC” waxay beddeshaa qiimaha doorsoomiyaha deegaanka TEST C:\DC .

Sida loo beddelo qiimaha doorsoomayaasha deegaanka ee Command Prompt

Taasi waxay u shaqeysaa sababtoo ah amarka setx wuxuu dib u qoraa qiimaha jira midka ugu dambeeya ee aad ku qorto. Sidaa darteed, haddii aad u isticmaasho amarkan dhowr jeer isla doorsoomiyaha, doorsoomuhu wuxuu hayn doonaa qiimihii ugu dambeeyay ee aad ku qortay.

Sida loogu daro qiimayaal badan doorsoomayaasha deegaanka iyadoo la isticmaalayo Command Prompt

FIIRO GAAR AH:^(NOTE:) Waxaad heli kartaa liiska dhammaan doorsoomayaasha deegaanka ee la heli karo adiga oo ku socodsiiya amarka dejisan^(set) ee Command Prompt (ma aha setx, iyo iyada oo aan wax xaddidaad ah lahayn). Si kastaba ha ahaatee, haddii aad hadda abuurtay ama aad wax ka beddeshay doorsoomayaasha deegaanka, waa in aad xidhid oo aad dib u furtaa Command Prompt si ay isbeddeladu u muuqdaan.

Sida loo arko dhammaan doorsoomayaasha deegaanka ee Command Prompt

Sida loo beddelo doorsoomayaasha deegaanka ee PowerShell

Waxaad sidoo kale ka abuuri kartaa ama wax ka beddeli kartaa qiimaha doorsoomayaasha deegaanka ee PowerShell . Amarka PowerShell ee taasi waa:

• [Deegaanka] :: SetEnvironmentVariable("variable_name", "variable_value","Isticmaal")^{([Environment]::SetEnvironmentVariable("variable_name","variable_value","User") )} haddii aad rabto inaad abuurto doorsooma deegaan isticmaale
• [Deegaan] :: SetEnvironmentVariable ("magaca_door", "variable_value","Machine")^{([Environment]::SetEnvironmentVariable("variable_name","variable_value","Machine"))} haddii aad rabto inaad abuurto doorsoom deegaan nidaam

Tusaale ahaan, waxaanu ku qornay [Environment] ::SetEnvironmentVariable("TEST","digitalcitizen.life","Isticmala")^{([Environment]::SetEnvironmentVariable("TEST","digitalcitizen.life","User"))} si aanu u abuurno doorsoome deegaan isticmaale oo loo yaqaan TEST oo leh qiimaha digitalcitizen.life. Si loo beddelo qiimaha doorsoomiyaha dambe, waxaan ku socodsiin karnaa isla amar anagoo adeegsanayna qiime kale. Sida^(Just) setx ee Command Prompt , amarkani^(setx) wuxuu dib u qoraa qiimaha doorsoomaha la cayimay mar kasta oo aad maamusho.

Sida loo dejiyo doorsoomayaasha deegaanka ee PowerShell

Haddii aad rabto inaad u qoondayso qiyam badan doorsoome, ku qor dhamaantood amarka, oo leh semicolons inta u dhaxaysa qiime kasta, sida hoos lagu muujiyey.

Sida loogu daro qiimayaal badan doorsoomiyaha deegaanka ee PowerShell

FIIRO GAAR AH:^(NOTE:) PowerShell , waxaad^(PowerShell) ka heli kartaa liiska dhammaan doorsoomayaasha deegaanka adiga oo ku socda Get-ChildItem Env: amarka. Si kastaba ha ahaatee, haddii aad hadda abuurtay ama aad wax ka beddeshay doorsoomayaasha deegaanka, waa inaad xidha oo dib u furtaa PowerShell^(PowerShell) si isbeddeladu u soo baxaan.

Sida loo arko dhammaan doorsoomayaasha deegaanka ee PowerShell

Sida loo nadiifiyo qiimaha doorsoomayaasha deegaanka ee Windows (laga bilaabo Command Prompt )

Haddii aad rabto inaad ka saarto qiimaha doorsoomayaasha deegaanka (inta aad ilaalinayso magaceeda), taas kuma samayn kartid jiirka iyo kiiboodhka daaqada Bey'ada Variables . ^{(Environment Variables)}Haddii aad dooratid doorsoome oo taabo Edit , waad tirtiri kartaa qiimihii, laakiin ma daabici kartid OK , maadaama badhankani uu cirraynayo. Sidaa darteed ma badbaadin kartid isbeddelladaada.

Sida loo nadiifiyo doorsoomayaasha deegaanka ee Windows 10

Si kastaba ha ahaatee, waxaad nadiifin kartaa qiimaha doorsoomayaasha deegaanka adigoo isticmaalaya Command Prompt . Si aad u dejiso doorsoomiyaha deegaanka ee Command Prompt , ku qor amarka setx variable_name “” . Tusaale ahaan, waxaan ku qornay 'sex TEST'^{(setx TEST “”)} oo doorsoomaha deegaanka hadda wuxuu lahaa qiime madhan.

Sida loo nadiifiyo doorsoomayaasha deegaanka iyadoo la adeegsanayo Command Prompt

Marka xigta, aan aragno sida meesha looga saaro doorsoomayaasha deegaanka.

Sida loo tirtiro doorsoomaha deegaanka ee Windows

Haddii aadan rabin inaad isticmaasho doorsoom deegaan gaar ah, ka dooro daaqada kala duwanaanshaha deegaanka . ^{(Environment Variables)}Markaas, taabo Delete . Daaqadaha^(Windows) ma waydiiso wax xaqiijin ah falkan. Sidaa darteed, haddii aad bedeshay maskaxdaada, waa inaad riixdaa Jooji^(Cancel) , si ka saarista aan loo dabaqin. Haddii aad rabto in tirtirku sii socdo, taabo OK .

Sida loo tirtiro doorsoomaha deegaanka ee Windows 10

Sida loo tirtiro doorsoomiyaha deegaanka ee Command Prompt

Si loo tirtiro doorsoomiyaha deegaanka ee Command Prompt , ku qor mid ka mid ah labadan amar, iyadoo ku xidhan nooca doorsoomuhu yahay:

• REG delete “HKCU\Environment” /F /V “variable_name” haddii ay tahay doorsoom deegaanka isticmaala, ama
• REG delete “HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment” /F /V “variable_name” haddi ay tahay doorsoome deegaan nidaam.

Tusaale ahaan, waxaan ku qornay REG delete “HKCU\Environment” /F /V “TEST” iyo doorsoomayaasha deegaanka TEST ayaa ka baxay astaanta isticmaalaha.

How to edit, clear, and delete environment variables in Windows -

Programmers, system administrators, and power users may need to work at some pоіnt with environment variables. Some may want to deletе an environment variable; others will want tо change its value, and so on. This guide shares how to edit or delete enνironment variаbleѕ, as well as how to unset environment variables in Windows:

Open the Environment Variables window

To make many of the edits shown in this article, you first need to open the Environment Variables window. This guide explains how to do that and shows you the basics about working with environment variables: What are environment variables in Windows?.

The Environment Variables window in Windows 10

If you want to skip reading it, one path that works the same in all versions of Windows is to open the Run window (Win + R), Command Prompt, or PowerShell and execute the command: rundll32.exe sysdm.cpl,EditEnvironmentVariables.

How to edit an environment variable in Windows

If you want to change the value of an existing environment variable, first select it in the Environment Variables window. Then, click or tap Edit.

You are shown a window where you can edit both the name and the value of the variable. Make the modifications you desire and press OK. Then, press OK one more time in the Environment Variables window.

Editing an environment variable

How to edit an environment variable from Command Prompt

You can create a new environment variable, or edit the value of an existing environment variable (but not its name) from the Command Prompt too. The command you have to enter is:

• setx variable_name “value” if you want to create a user environment variable
• setx variable_name “value” /m if you’re going to create a system environment variable

For example, we typed setx TEST “C:\digitalcitizen” and created a user variable named TEST with the value C:\digitalcitizen.

How to set an environment variable using Command Prompt

If we want to change the value of an environment variable, we can run the same setx command but specify a new value for the variable. For instance, executing setx TEST “C:\DC” changes the value of the TEST environment variable to C:\DC.

How to change the value of an environment variable in Command Prompt

That works because the setx command rewrites the existing value with the last one you type. Therefore, if you use this command multiple times on the same variable, the variable will keep the last value that you typed.

How to add multiple values to an environment variable using Command Prompt

NOTE: You can get a list of all the environment variables available by running the set command in Command Prompt (not setx, and without any parameters). However, if you just created or edited an environment variable, you must close and reopen Command Prompt for the changes to show up.

How to edit an environment variable from PowerShell

You can also create or edit the value of an existing environment variable from PowerShell. The PowerShell command for that is:

• [Environment]::SetEnvironmentVariable("variable_name","variable_value","User") if you want to create a user environment variable
• [Environment]::SetEnvironmentVariable("variable_name","variable_value","Machine") if you want to create a system environment variable

For instance, we typed [Environment]::SetEnvironmentVariable("TEST","digitalcitizen.life","User") in order to create a user environment variable called TEST with the value digitalcitizen.life. To change the value of the variable later, we can run the same command using a different value. Just like setx in Command Prompt, this command rewrites the value of the specified variable each time you run it.

How to set an environment variable with PowerShell

If you want to assign multiple values to a variable, type all of them in the command, with semicolons between each value, as illustrated below.

How to add multiple values to an environment variable in PowerShell

NOTE: In PowerShell, you can get a list of all the environment variables by running the Get-ChildItem Env: command. However, if you just created or edited an environment variable, you must close and reopen PowerShell for the changes to show up.

How to clear the value of an environment variable in Windows (from Command Prompt)

If you want to remove the value of an environment variable (while keeping its name), you cannot do that with the mouse and keyboard from the Environment Variables window. If you select a variable and press Edit, you can delete the value, but you cannot press OK, as this button gets grayed out. Therefore you cannot save your changes.

How to clear an environment variable in Windows 10

However, you can clear the value of an environment variable using Command Prompt. To unset an environment variable from Command Prompt, type the command setx variable_name “”. For example, we typed setx TEST “” and this environment variable now had an empty value.

How to clear an environment variable with Command Prompt

Next, let’s see how to remove an environment variable.

How to delete an environment variable in Windows

If you no longer want to use a particular environment variable, select it in the Environment Variables window. Then, press Delete. Windows does not ask for any confirmation of this action. Therefore, if you have changed your mind, you must press Cancel, so that the removal is not applied. If you want the deletion to go ahead, press OK.

How to delete an environment variable from Command Prompt

To delete an environment variable from Command Prompt, type one of these two commands, depending on what type that variable is:

• REG delete “HKCU\Environment” /F /V “variable_name” if it’s a user environment variable, or
• REG delete “HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment” /F /V “variable_name” if it’s a system environment variable.

For example, we typed REG delete “HKCU\Environment” /F /V “TEST” and our TEST environment variable was gone from the user’s profile.

How to unset an environment variable in Windows using Command Prompt

How to delete an environment variable from PowerShell

To unset and delete an environment variable from PowerShell, type the command:

• [Environment]::SetEnvironmentVariable("variable_name", $null ,"User") if it’s a user profile variable, or
• [Environment]::SetEnvironmentVariable("variable_name", $null ,"Machine") if it’s a system-wide variable.

For example, we typed [Environment]::SetEnvironmentVariable("TEST", $null ,"User") and this environment variable was gone from the user’s profile.

That’s it!

Why did you want to learn how to edit and delete environment variables in Windows?

You now know how to do all that. But why did you want to change or edit environment variables? Was it because there were leftover variables on your system from certain apps that you no longer used? Or was it because you have a special setup, and you need to work with environment variables? Let us know in the comments section below.
