A critical emergency fix from Microsoft, released in late March as patch KB5085516, intended to resolve login issues with Microsoft applications, has unexpectedly created a new problem for some users.
Reports are surfacing that the update is rendering Windows 11 unusable in a fundamental way: users are finding they can no longer move or resize windows on their affected computers. The inability to interact with windows in this basic manner severely hinders functionality.
The issue appears to be concentrated on Windows 11 25H2 Pro systems. Users who installed KB5085516 are experiencing the problem, but crucially, uninstalling the update immediately restores normal window behavior.
Currently, Microsoft has not officially acknowledged this new issue on the support page for KB5085516, maintaining its statement that no problems with the update have been identified. The extent of the problem – whether it’s limited to a few cases or widespread – remains unclear.
If you’re running Windows 11 25H2 Pro and have installed KB5085516, and are now facing difficulties moving or resizing windows, uninstalling the update is a potential solution to restore functionality to your system.
