Forcing modified Sysprep configurations

You can customize Sysprep's behavior to some extent by modifying the XML files in this folder:

C:\Windows\System32\Sysprep\ActionFiles

One snag you might hit after doing that is that Sysprep could fail to "validate your Windows installation" even after you deal with Candy Crush. Somehow, Sysprep detects that it's been tampered with and disables itself. You can undo that by tweaking a Registry setting. Navigate to this key:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sysprep

If there's a SysprepCorrupt value set to 1, change its data to 0. Assuming everything else about your Windows installation is good, that should let you run Sysprep.
