First reported by Bleeping Computer, Microsoft is now preventing Windows 11's 24H2 update from being sent out to machines that have a selection of recent Ubisoft games installed on them.
A number of users have reported persistent, unworkable crashing, sometimes on startup, when trying to play the affected games. «After installing Windows 11, version 24H2, you might encounter issues with some Ubisoft games.
These games might become unresponsive while starting, loading or during active gameplay,» Microsoft wrote in a help article about 24H2's known issues. «To safeguard your Windows update experience, we have applied a compatibility hold on devices with these games installed.
These devices will not be offered to install Windows 11, version 24H2 via the Windows Update release channel.» If you've already had 24H2 installed and don't want to wait for a fix to play these games, your best bet is probably rolling back to version 23H2 for the time being.
24H2 began a phased rollout at the beginning of October, and Bleeping Computer found numerous posts on Reddit and the Microsoft answers forums reporting issues with the games since the rollout.
