PowerShell script that can help you fix Windows patch installation issues

Here is a PowerShell script that can help you fix Windows patch installation issues:

# Check if the current user is an administrator $currentUser = [Security.Principal.WindowsIdentity]::GetCurrent() $adminPrincipal = New-Object Security.Principal.WindowsPrincipal($currentUser) $isAdmin = $adminPrincipal.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator) if ($isAdmin -ne $True) { Write-Output "This script requires elevated permissions. Please run it as an administrator." Exit } # Clear the Windows Update cache Write-Output "Clearing the Windows Update cache..." Get-ChildItem -Path "C:\Windows\SoftwareDistribution\Download" | Remove-Item -Force # Reset the Windows Update components Write-Output "Resetting the Windows Update components..." net stop wuauserv net stop cryptSvc net stop bits net stop msiserver ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 catroot2.old net start wuauserv net start cryptSvc net start bits net start msiserver # Check for updates and install them Write-Output "Checking for and installing updates..." Get-WindowsUpdate | Install-WindowsUpdate # Check the installation status of the updates Write-Output "Checking the installation status of the updates..." Get-WindowsUpdate | Get-WindowsUpdateResult

This script first checks if the current user has administrative permissions. If not, it will exit the script. Then it clears the Windows Update cache, resets the Windows Update components, checks for and installs updates, and finally checks the installation status of the updates.
