GoKawiilWindows 11 KB5120998 update breaks custom mouse cursor settings, Microsoft confirms
Microsoft has acknowledged that its optional KB5120998 preview update, released August 27, 2026, is causing custom mouse cursor personalizations to revert to default settings on Windows 11. Affected users report high-DPI cursors being swapped for standard white ones and custom animations disappearing, with no way to restore prior settings. The company says it is investigating and is asking impacted users to submit reports through the Feedback Hub.
GoKawiil's interpretation of the reporting above, not reported fact.
This marks another instance of Microsoft's optional preview updates introducing regressions before wider rollout, following recent problems with USB input devices in recovery mode and disappearing cursors in Outlook. Since users can't currently undo the cursor reset, it highlights a gap in Microsoft's update rollback tools for cosmetic settings, not just functional ones.
- KB5120998 resets custom mouse cursor personalization on Windows 11 24H2 and 25H2.
- Affected users cannot currently restore their previous cursor settings.
- Microsoft is investigating the cause and collecting feedback via the Feedback Hub.
