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.
Microsoft has clarified that a mouse personalization reset bug tied to the August 2026 preview update KB5120998 only impacts Windows 11 devices set to non-English locales. The company found that certain code components fail to load correctly on these systems, causing cursor and animation settings to revert to defaults instead of user preferences. The update, which also brings Start menu and taskbar changes, is optional and only installs automatically if users have enabled the setting to receive updates as soon as they're available.
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.
