Update KB5051987, released last week for Windows 11 24H2, was supposed to bring important security fixes and quality-of-life improvements. However, some users who installed the cumulative February update are now reporting numerous problems,

Microsoft's latest Patch Tuesday fixed several bugs but triggered several problems. Some users are struggling just to install the security update.

Windows 11's KB5051987 update is causing users problems with File Explorer and, in rare cases, breaking the operating system entirely.

With updates KB5051989 and KB5051987, users on both Windows 11 23H2 and 24H2 are getting security fixes and quality-of-life improvements.

With Microsoft set to end support for Windows 10 later this year, now is not the time for major issues to break PCs thanks to Windows 11 updates. But that appears to be what's happening, as the latest Windows 11 24H2 update (KB5051987) is reportedly causing major issues with File Explorer (via Windows Latest) and other software.
