Can't uninstall windows update

Hey there, Toan2491,

Welcome to Microsoft Community.

If you're unable to uninstall the problematic Windows Update(KB5023696) through the standard method, you could try using the Command Prompt or Windows Powershell to remove the update. Here's how:

1. Click Start and type cmd in the Start menu search box. Right-click it and click Run as administrator.
2. In the command prompt, type in the following command format and hit Enter to proceed the process:

    wusa /uninstall /kb:5023696
   

Please feel free to let me know if you have any further updates, thanks.

Have a great day and stay safe!

Best regards

I did as you said and met an error: Window Update Standalone Installer - Installer encountered an error: 0x800f0905

What can i do now? Thanks for reply

My recent update was the Security Update for Microsoft windows(KB5023696). After the update I had a blue screen error. I went into safe mode and tried to uninstall the update but apparently "it is required by my computer and cannot be uninstalled". What could cause the blue screen error and what are possible ways of fixing it?

Thanks for your update. Error 0x800f0905 is typically caused by a file corruption or a conflict with another process. Here are some additional steps you can try to troubleshoot the issue:

1. Run System File Checker (SFC) and DISM: a. Open Command Prompt (Admin) or Windows PowerShell (Admin) with administrative privileges. b. Type sfc /scannow and press Enter. Wait for the process to complete. It may take some time. c. If the SFC scan doesn't fix the issue, type the following DISM commands and press Enter after each:

    Dism /Online /Cleanup-Image /CheckHealth 
   
    Dism /Online /Cleanup-Image /ScanHealth 
   
    Dism /Online /Cleanup-Image /RestoreHealth
   

   d. Once the DISM process is complete, restart your computer and try uninstalling the update again.
2. Reset Windows Update components: a. Open Command Prompt (Admin) or Windows PowerShell (Admin) with administrative privileges. b. Type the following commands and press Enter after each to stop the Windows Update services:

    net stop wuauserv 
   
    net stop cryptSvc 
   
    net stop bits 
   
    net stop msiserver 
   

   c. Rename the SoftwareDistribution and Catroot2 folders by typing the following commands and pressing Enter after each:

    ren C:\Windows\SoftwareDistribution SoftwareDistribution.old 
   
    ren C:\Windows\System32\catroot2 catroot2.old 
   

   d. Restart the Windows Update services by typing the following commands and pressing Enter after each:

    net start wuauserv 
   
    net start cryptSvc 
   
    net start bits 
   
    net start msiserver
   

   e. Close the Command Prompt or PowerShell and try uninstalling the update again.
3. If the issue persists, you can try booting your computer in Safe Mode and then attempt to uninstall the update.
4. If all else fails, maybe it worth consider backing up your important data and performing a clean installation of Windows.

Please keep us posted.

Currently having the same issue with Security Update KB5033375. I used to be able to uninstall it, now whenever I click uninstall nothing happens. I just reinstalled Win 11 and it still happened, I'll have to do it again I suppose, I don't know what else to do.
