Uninstall a Windows Update by KB (PSWindowsUpdate)

Minimal helper and examples to remove an installed Windows update by its KB number using the PSWindowsUpdate module.

Requirements

• Run PowerShell as Administrator.
• Module: PSWindowsUpdate (install if needed: Install-Module PSWindowsUpdate -Scope CurrentUser).
• A reboot may be required after removal.

Quick commands (no wrapper)

# List installed updates matching the KB
Get-WindowsUpdate -IsInstalled -KBArticleID KB5028952

# Uninstall (no auto-restart)
Remove-WindowsUpdate -KBArticleID KB5028952 -NoRestart -Confirm:$false

Script usage

If you saved the wrapper as Remove-KB.ps1:

# Example
.\Remove-KB.ps1 -KB KB5028952 -NoRestart

Notes

• Some updates (especially Servicing Stack Updates) cannot be uninstalled.
• If removal via PSWindowsUpdate fails for a cumulative update, find the exact package name and try DISM:

  DISM /Online /Get-Packages
  DISM /Online /Remove-Package /PackageName:<ExactName> /Quiet /NoRestart
  

• Logs: C:\Windows\Logs\WindowsUpdate\windowsupdate.log and C:\Windows\Logs\CBS\CBS.log.
