The problem occurs because Windows Update files get corrupted due to the issue. Hence, removing the corrupted files solves the issue, which can be done easily by following these steps:
Press Win+R keys to open the Run dialog
Type “C:\Windows\SoftwareDistribution\Download” and press OK
File Explorer gets open – delete all the files/folders in this directory (in case you can’t delete the files, boot Windows into ‘safe mode’ and then try deleting the files)
Restart your PC and try running the Windows Update again
In case the above methods didn’t work, then follow these steps:
1. Paste the below path in File Explorer and open it. After that, right-click on Command Prompt and choose “Run as administrator”.
C:\Users\Beebom\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\System Tools
2. Now, type start powershell and hit enter.
3. Once you are in the PowerShell window, execute the below command and wait for a while.
Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -verbose }
4. After the installation is completed, restart the PC and you will have the Start Menu working again.
