Windows 11 version KB5120998 was released as an optional update, introducing new customization features such as the ability to move and resize the taskbar and improvements to Windows Search. However, the update has introduced several bugs, including issues with the mouse cursor, which may not appear or may be incorrectly sized, and problems with wallpaper settings reverting to black after restarts. Users have also reported blurry fonts on high-resolution displays. Microsoft is aware of these issues and is working on a solution. Users experiencing these bugs can roll back the update by navigating to Settings > Windows Update > Update History > Uninstall and selecting KB5120998, without losing essential security patches.
