Fix Windows Update Error C8000266?

Windows Update is used to keep Microsoft Windows and othеr Microsoft programs updated. Being one of the most essential services for the operating sуstem, it downloads and installs the security updates regularly to Windоws. However, they can cause errors at times that bеcomes a highly disturbing moment at that situation. One such error is Windows Update Error C8000266.

C8000266: Windows Update encountered an unknown error

In this guide, we have explained some quick fixes that will possibly help you to get rid of this problem. So, let’s get started.

Windows Update Error C8000266

To fix Windows Update Error C8000266, follow the below suggestion:

1. Run Windows Update Troubleshooter
2. Reset the Windows Updates Components

Let us see them in details:

1] Run Windows Update Troubleshooter

The Windows Update troubleshooter is a great built-in tool that can certainly fix most of the common update related issues on the computer. The procedure to run this application is as follows:

To get it started, open the Windows Settings (Win+I) first.

Then select Update & Security > Troubleshoot > Additional troubleshooters.

On the next page, select Windows Update and then click Run the troubleshooter button.

Wait for a while until it detects and solves the problem throughout.

Once it completes the process, close the troubleshooter, and restart your device.

Furthermore, you can also try running the Windows Update Online Troubleshooter.

Now go to the Windows Update and try to install the pending update.

If you’re still facing the problem move down to the next potential solution.

2] Reset the Windows Updates Components

If running Windows Update Troubleshooter doesn’t fix the problem, you can reset the Windows Updates Components manually. Here is a quick guide you can use to do so:

Open Run dialog box using Win+R keyboard shortcut.

Type in cmd and press Ctrl+Shift+Enter to open an elevated command prompt.

If UAC prompts on the screen, click Yes to grant them permission.

On the elevated command prompt window, type in the following commands and hit enter on each line.

net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc

This will stop running the Background Intelligent Transfer Service or BITS, Windows Update service, and Cryptographic service.

Now you need to reset Windows Update components by removing all the qmgr*.dat files from your device.

To do so, type the below command-line in the command prompt and hit enter to execute it.

Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"

To confirm the deletion, type Y from your keyboard.

Next, rename the SoftwareDistribution and catroot2 folders.

To do that, type the following commands in the command prompt window. Also, make sure to hit enter after you type each command.

Ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak
Ren %systemroot%\system32\catroot2 catroot2.bak

Next, you have to reset the BITS service and the Windows Update service to its default security descriptor

To do this, type the below commands in the elevated command prompt window:

sc.exe sdset bits D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)
sc.exe sdset wuauserv D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)

Press enter to execute the command and hit enter after each one.

Type the below text code in the command prompt window to move to the System32 directory. Then press Enter.

cd /d %windir%\system32

Now input the following commands and make sure to hit enter after each command you type there.

regsvr32.exe atl.dll
regsvr32.exe urlmon.dll
regsvr32.exe mshtml.dll
regsvr32.exe shdocvw.dll
regsvr32.exe browseui.dll
regsvr32.exe jscript.dll
regsvr32.exe vbscript.dll
regsvr32.exe scrrun.dll
regsvr32.exe msxml.dll
regsvr32.exe msxml3.dll
regsvr32.exe msxml6.dll
regsvr32.exe actxprxy.dll
regsvr32.exe softpub.dll
regsvr32.exe wintrust.dll
regsvr32.exe dssenh.dll
regsvr32.exe rsaenh.dll
regsvr32.exe gpkcsp.dll
regsvr32.exe sccbase.dll
regsvr32.exe slbcsp.dll
regsvr32.exe cryptdlg.dll
regsvr32.exe oleaut32.dll
regsvr32.exe ole32.dll
regsvr32.exe shell32.dll
regsvr32.exe initpki.dll
regsvr32.exe wuapi.dll
regsvr32.exe wuaueng.dll
regsvr32.exe wuaueng1.dll
regsvr32.exe wucltui.dll
regsvr32.exe wups.dll
regsvr32.exe wups2.dll
regsvr32.exe wuweb.dll
regsvr32.exe qmgr.dll
regsvr32.exe qmgrprxy.dll
regsvr32.exe wucltux.dll
regsvr32.exe muweb.dll
regsvr32.exe wuwebv.dll

This will re-register all the respective BITS files and Windows Update related DLL files

Now you need to reset the network configurations that might be the role of the problematic error.

To do so, type in the below command-line and hit enter after each one.

netsh winsock reset
netsh winsock reset proxy

Once it is all completed, you need to restart the services you stopped it earlier like Background Intelligent Transfer Service or BITS, Windows Update, and Cryptographic services.

To do so, again go to the command prompt and type in the below command line. Also, don’t forget to press enter after each command.

net start bits
net start wuauserv
net start appidsvc
net start cryptsvc

Finally, type Exit in the Command Prompt to close the window.

Once you complete the entire process, restart your Windows PC to apply the changes.

After it starts up, go to the Windows Updates and try to install the pending updates available on the computer.

We hope the above-mentioned method would help you to resolve this issue.
