Microsoft Resolves Issues with Mouse Settings

On September 11, 2026, Microsoft released an update that addresses a known issue in Windows 11. Following the installation of the August update KB5120998, some users experienced unwanted resets of their mouse settings. This disruption particularly affected the configuration of pointer speed and button assignments. The company has confirmed in an official statement that the new September updates resolve these issues.

Users who were affected by the resets should now be able to use their individual settings without further disruptions. Microsoft recommends installing the update promptly to restore full mouse functionality. The issues primarily occurred for users who had installed the preview version of the update. Microsoft had previously warned about the difficulties and promised to develop a solution. User feedback was crucial in identifying and resolving the problem.

In addition to the mouse settings, other minor bugs in Windows 11 have also been fixed. These include improvements to system stability and security updates that close potential vulnerabilities. Microsoft has emphasized that user security is a top priority and that continuous efforts are being made to improve the software. The September updates are part of Microsoft's regular patch cycle, which provides new security and feature updates every month. Users can install the updates through the Windows Update feature.

Microsoft has pointed out that installing the updates is essential for maintaining system security. The exact number of affected systems has not been disclosed; however, Microsoft estimates that several thousand users were impacted by the resets. The company has also provided detailed instructions on how users can check and adjust their settings after installing the update. Microsoft plans to roll out the September updates to all users by the end of the month. The distribution will be gradual to ensure that all systems can be updated smoothly.

Users should regularly check for updates to ensure they receive the latest security and feature enhancements. The issues with mouse settings are not the first time Microsoft has faced such challenges. Similar incidents have occurred in the past, but they were typically resolved quickly. Microsoft is committed to continuously improving the user experience and responding to feedback. The security vulnerability CVE-2026-1234, discovered in connection with the August update, reportedly affects around 50,000 systems in Germany, according to the BSI. Microsoft has also taken appropriate measures to ensure user security in this regard.
