Ok so apparently I did it (WOW!!!)
My solution was disabling
- Hyper-V
- VM Platform
- Windows Hypervisor Platform
- Windows Sandbox
- WSL
I don't exactly know which feature PCRPF is connected with, but hey it worked.

Hello, I am trying to perform an ISO in-place upgrade to Windows 24H2 because of Windows defender UI being broken, but the process fails with a message stating that the PCRPF component is considered critical on the source system but is not required by the target system. My OS was previously Win10, and was then upgraded to Win11, now is at version 24H2.
I have checked using PowerShell and DISM, and the component does not appear among the optional features or installed packages. However, I found references to "pcrpf" in both the WinSxS folder and the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\Winners.
How can I safely resolve this issue and complete the upgrade? Is it safe to manually remove these references from the registry, or is there a recommended procedure from Microsoft to handle this kind of (probably) leftover component? I have already tried running DISM /online /cleanup-image /startcomponentcleanup /resetbase and sfc /scannow with no success.
Any advice or official guidance would be greatly appreciated!

It didn’t work? That’s unfortunate.

Try reinstalling Windows by downloading a repair version through Windows Update.
For detailed instructions, please refer to the support article:

2025-08-03T22:48:21.86+00:00 I had already did that (successfully) but it neither solved WinDefender nor removed the PCRPF files (I'm guessing it's a less strict migration).
Still, I'm doing it again right now, but I doubt it'll solve. -
