HI,

After many hours of testing I managed to update to Windows 11 24H2 26100.1742 (the initial public release) with no CPU issue, using the following install order:

 

Download Win 11 24H2 26100.1150 from here:

https://uupdump.net/selectlang.php?id=c1da54e1-2cf1-4534-ba44-61251a6de142


1) Install or upgrade to Win 11 24H2 26100.1150 with no internet connected.
2) Pause all Windows update for now until a future fix that hopefully will be released sometime.
3) Install kb5041571 (Win 11 26100.1457)
4) Install kb5041865 (Win 11 26100.1591)
5) Install kb5043080 (Win 11 26100.1742)

6) Reboot and then connect the internet.


Any update after these cause the CPU issue again so keep the updates paused for now.

 

What this method does is bypass the install of kb5044030 which causes the CPU issue.

If you already have kb5044030 installed - uninstalling it does not fix the CPU issue !!
