Microsoft has fixed a bug introduced by the optional KB5120998 preview update that caused mouse cursor personalization settings to revert to defaults on some Windows 11 24H2 and 25H2 devices, particularly non-English installations. The company says the September 8 KB5124008 cumulative update resolves the issue and is urging affected users to install it, noting that uninstalling the buggy update did not restore settings.
GoKawiil's interpretation of the reporting above, not reported fact.
The episode shows how even optional preview updates can quietly break core system functionality across specific language configurations, undermining confidence in Microsoft's staged rollout process. It also highlights that some regressions can't be undone by simple rollback, forcing users to wait for an official fix rather than self-remediate.

Logitech MX Master 3S Wireless Mouse — If Windows keeps resetting your mouse personalization, a mouse with its own software profiles is a nice hedge — the MX Master 3S stores button and pointer customization through Logi Options+ rather than relying solely on Windows settings. It's a comfortable, quiet-click ergonomic mouse that works across multiple computers, so a flaky update won't ruin your workflow.
