This lovely recent KB4534271 has corrupted the gpt.ini file on a few of our customers AD’s.

This is why you should always keep your Domain and DC GPO’s pristine, cause had to restore them in order for GPO processing to work again.

Elevated CMD:
1. dcgpofix /ignoreschema /target:domain.local
2. Yes
3. Yes
4. on Desktops affected, gpupdate /force
5. No, to log off, restart or…
6. shutdown.exe /r /t 0

So annoying!
