BleepingComputer • • technology
Key Points:
- Microsoft confirmed that the KB5120998 August 2026 non-security preview update is causing mouse cursor personalization settings on Windows 11 to be changed or reset automatically.
- Affected users report that previous mouse settings cannot be restored after the update reverts them, with issues including appearance regressions and animation changes.
- The update replaces high-DPI cursors with larger, white cursors and resets custom cursor animations to default, and Microsoft is still investigating the root cause.
- KB5120998, released on August 27, 2026, includes improvements to the Start menu, taskbar, and Windows search for Windows 11 versions 25H2 and 24H2, but is optional and must be manually installed unless auto-update is enabled.
- Microsoft has asked users experiencing these mouse issues to report them via the Feedback Hub and has previously addressed other mouse-related problems, including a critical fix for disabled USB mice and keyboards in Windows Recovery Environment.
