The update KB5051987 for Windows 11 24H2 aimed to enhance security and user experience but has led to numerous issues. Users have reported unresponsiveness in File Explorer, with the application freezing or failing to open. Some users experience a black desktop, and attempts at system restoration or reinstallation have not resolved the problems. Many users are unable to install the update due to persistent error messages, leading to an endless update loop. Clearing the software distribution folder may help, but patience is required. Camera functionality has also been affected, with systems failing to recognize webcams. Additional issues include performance drops during gaming, installation errors in Windows Sandbox, glitches in taskbar preview animations, and some users being unable to boot into Windows. Uninstalling the update is an option for those facing severe issues, but it leaves systems vulnerable until Microsoft addresses the problems.
