Windows 11 Update Resets Mouse Settings for Some Users
Microsoft has acknowledged an issue affecting Windows 11 users who installed the KB5120998 update, which was released on August 27, 2026. The update, a non-security preview, is reverting mouse settings to certain standard settings, causing appearance regressions and intermittent animation changes.
Affected users have reported that their high-DPI mouse cursors are being replaced with larger, white cursors, and custom cursor animations are reverting to standard settings. Furthermore, attempts to restore the previous cursor customization are reportedly unsuccessful.
Microsoft is still investigating the root cause of this issue and has asked affected customers to file a report via the Feedback Hub if they're experiencing this problem. The KB5120998 update was released with improvements to the Start menu, taskbar, and Windows search for Windows 11 versions 25H2 and 24H2.
