Windows 11 21H2 upgrade to 22H2 failing @ 64%

Hi...

 

I have a bunch of machines running Win11 21H2 which need updating to 22H2. I'm using WSUS and have downloaded Windows 11, version 22H2 x64 2023-10B.

For 30 minutes the machine will download and install the upgrade and complete any other bits it needs to compile, after successful completion of the initial phase I then reboot.

During the next phase there's a couple of reboots and the upgrade process appears to be going well, the percentage indicator increases fairly quickly, and then suddenly stops at 64%. It says Updating drivers and just sits there for about 2 hours, eventually increasing to 87%, and that's were it remains for an eternity.

I haven't had any problems running Win11 21H2 these past few months, with no driver issues or dodgy applications. This should be a simple in-place update to 22H2 on an OS that is stable, I don't understand why it would hang.

I've disabled AV and put the test machine in an OU that removes Group Policies.

A new 22H2 image has been created which installs and works without issue.... however, I don't won't to rebuild all the machines.

      Hi... yep, been through the logs, there's a lot to trawl through.

      From additional testing it looks like a GPO might be causing the problem, though it's proving difficult to pinpoint because I've run a test without any GPO's assigned but it still fails.

      I built a machine today using a standard 21h2 image, without making it a domain member, and successfully upgraded to 23h2.

      After another rebuild and making it a domain member, the upgrade failed.

        Hi

        Some GPO settings don't revert to the default if they are unassigned. Maybe one of these is causing the problem. Does the 23H2 update fail on clients with applied GPOs?
