AppxSysprepCleaner

A PowerShell script to automatically detect and remove AppX packages that block Sysprep from completing on Windows 11.

Why?

During the image capture process using MDT and Sysprep, AppX packages like Microsoft.Copilot or Microsoft.StartExperiencesApp may cause Sysprep to fail with error 0x80073cf2.

This script reads Sysprep's log, identifies problematic AppX packages, and removes them cleanly from the system and all user profiles.

Features

• Parses setupact.log automatically
• Detects AppX packages that block Sysprep
• Removes them for all users
• Removes provisioned packages from the system image

How to use

Run the script as administrator in PowerShell:

Set-ExecutionPolicy Bypass -Scope Process -Force
.\AppxSysprepCleaner.ps1

Then re-run sysprep.exe as usual.
