Windows 11’s emergency March update is breaking window management

In late March, Microsoft rolled out emergency patch KB5085516, aimed at resolving issues with Microsoft app logins. However, the update has inadvertently introduced a new set of challenges for users of Windows 11 25H2 Pro. Reports indicate that after installing this patch, users are facing difficulties in moving or resizing application windows, significantly hampering their daily computing tasks.

Emerging Issues Post-Update

According to a report from BornCity, affected users have found that the functionality to manipulate windows has been compromised. The inability to move or resize windows creates a frustrating experience, as these actions are fundamental to efficient workflow. Fortunately, users have discovered that uninstalling KB5085516 restores the previous window management capabilities, allowing them to regain control over their desktop environment.

As of now, Microsoft has not officially acknowledged these new complications on their support page for KB5085516, which continues to state, “Microsoft is currently not aware of any issues with this update.” This raises questions about whether the window management problems are isolated incidents or indicative of a broader issue affecting a wider range of PCs.

For users experiencing these challenges, the temporary solution appears to be uninstalling the problematic update. This step may provide immediate relief while awaiting further guidance from Microsoft regarding the situation.
