Sysprep needing to validate Windows when selecting generalize


This Content is from SuperUser. Question asked by Tempus Nomen

I’ve been trying to create a WIM of my modified Windows 11 install. To that end, I’ve been attempting to have Sysprep clean Win 11 using the “generalize” option. Yet, in Sysprep, every time I tick “generalize” & click OK, a dialog saying “Sysprep was not able to validate your Windows installation” pops up.

This doesn’t seem to be the case as checking System > Activation > Activation state says it’s “Active”. It seems like the license for the OEM Win 10 this laptop came with carried over for Win 11.

So far, every once in a while, I’ve been able to trigger a reboot/shutdown with generalize when I use tools that disrupts the activation state of Windows, like say, running KMSpico or manually entering a different product key.

I need a way to be able to reboot/shutdown with generalize selected without these fickle tricks of disrupting the activation state.
