Uninstall Windows Updates

Custom PowerShell Script to uninstall Windows Updates.

PowerShell Script

The following is the Uninstall Windows Update KB 5000802 sample PowerShell script. Copy it and save it as a .ps1 file or download it from here http://faronics.org/proservices/UninstallWU.ps1.

wusa /uninstall /kb:5000802 /quiet /forcerestart

Note that this example is specific to KB 5000802; you will need to replace the Patch KB Number with the Patch KB Number of the Windows Update that you wish to uninstall.

1. Edit the script to replace the Patch KB Number (5000802 in the example above) with the Patch KB Number to be uninstalled.

2. Optional: Remove /forcerestart from the script to prevent an instant restart.

It's recommended that the /forcerestart remains in the script but it is not mandatory.

3. Save the script as a .ps1 file.

4. Self-host the script - see Quick Guide to Self-Hosting Custom Scripts.
