Microsoft is investigating reports that Windows 11 update KB5120998 can reset mouse cursor personalization settings and cause problems with custom cursor animations.<\/p>\n\n\n\n

The issue affects Windows 11 version 24H2 and Windows 11 version 25H2. Microsoft says some high-DPI cursors may be replaced by larger white cursors, while custom cursor animations can revert to standard Windows settings.<\/p>\n\n\n\n

What Is the Windows 11 KB5120998 Mouse Cursor Problem?<\/h2>\n\n\n\n

Microsoft says it has received reports that mouse cursor personalization settings can change or return to standard settings after installing Windows updates released on August 27, 2026, including KB5120998.<\/p>\n\n\n\n

Reported problems include changes to the cursor’s appearance and intermittent animation problems.<\/p>\n\n\n\n

Some users have found that high-DPI cursors are replaced by larger white cursors. Custom cursor animations can also return to standard Windows settings.<\/p>\n\n\n\n

Microsoft says attempts to restore the previous cursor customization may not work in some cases.<\/p>\n\n\n\n

Windows Latest also reported cases where users experienced changes in cursor size, color, and custom schemes after installing KB5120998. Some affected users said uninstalling the update restored their previous cursor settings.<\/p>\n\n\n\n

Which Windows 11 Versions Are Affected?<\/h2>\n\n\n\n

Microsoft lists the following versions as affected:<\/p>\n\n\n\n

    \n
  • Windows 11 version 24H2<\/li>\n\n\n\n
  • Windows 11 version 25H2<\/li>\n<\/ul>\n\n\n\n

    Windows Server is not listed as affected.<\/p>\n\n\n\n

    KB5120998 raises Windows 11 25H2 to OS Build 26200.9278 and Windows 11 24H2 to OS Build 26100.9278.<\/p>\n\n\n\n

    Is KB5120998 a Required Windows 11 Update?<\/h2>\n\n\n\n

    No. KB5120998 is an optional non-security preview update. Microsoft released it on August 27, 2026. <\/p>\n\n\n\n

    Users can find optional updates through Settings > Windows Update > Advanced options > Optional updates<\/strong>.<\/em><\/p>\n\n\n\n

    The update also introduces several Windows 11 changes, including new taskbar positioning options, a smaller taskbar setting, and additional Start menu customization.<\/p>\n\n\n\n

    Because KB5120998 is optional, users who have not installed it can wait while Microsoft investigates the cursor problem.<\/p>\n\n\n\n

    What Should You Do If KB5120998 Changed Your Mouse Cursor?<\/h2>\n\n\n\n

    Microsoft currently asks affected users to submit a report through the Windows Feedback Hub.<\/p>\n\n\n\n

    You can open Feedback Hub by pressing Windows key + F<\/strong>. Microsoft says these reports will help with its investigation.<\/p>\n\n\n\n

    Microsoft has not published an official workaround or fix for the cursor problem.<\/p>\n\n\n\n

    Windows Latest reports that uninstalling KB5120998 restored normal cursor behavior for some affected users. This is a reported workaround, not Microsoft’s official recommendation.<\/p>\n\n\n\n

    Users who are not experiencing the problem do not need to remove the update based on Microsoft’s current guidance.<\/p>\n\n\n\n

    Has Microsoft Confirmed That KB5120998 Causes the Bug?<\/h2>\n\n\n\n

    Not yet.<\/p>\n\n\n\n

    Microsoft has acknowledged the reports and lists KB5120998 as the originating update on its Windows release-health dashboard. However, the company says it is still investigating whether the problem is caused by Microsoft.<\/p>\n\n\n\n

    This distinction is important. The issue is officially listed as Reported<\/strong>, rather than Confirmed<\/strong>.<\/p>\n\n\n\n

    Why Does the KB5120998 Cursor Bug Matter?<\/h2>\n\n\n\n

    The problem is mainly a personalization issue, but it can be disruptive for users who depend on larger, high-DPI, animated, or customized mouse cursors.<\/p>\n\n\n\n

    Accessibility can also be a concern. Some users deliberately adjust cursor size, color, and appearance to make the pointer easier to see.<\/p>\n\n\n\n

    If Windows resets those settings and prevents users from restoring them, the problem can affect more than the appearance of the desktop.<\/p>\n\n\n\n

    Sebertech Analysis<\/h2>\n\n\n\n

    There is currently an unusual difference between two official Microsoft pages.<\/p>\n\n\n\n

    Microsoft’s Windows release-health dashboard lists the mouse customization problem as a reported issue linked to KB5120998 and says the company is investigating it.<\/p>\n\n\n\n

    However, Microsoft’s main KB5120998 support page still states that Microsoft is not currently aware of any issues with the update.<\/p>\n\n\n\n

    The release-health dashboard was updated on August 28, 2026, so it currently provides the more specific information about the cursor problem.<\/p>\n\n\n\n

    This difference may disappear once Microsoft updates the KB5120998 support page.<\/p>\n\n\n\n

    What Is Still Unknown?<\/h2>\n\n\n\n

    Microsoft has not confirmed the technical cause of the cursor problem.<\/p>\n\n\n\n

    It is also unclear why some Windows 11 PCs are affected while others are not.<\/p>\n\n\n\n

    There is currently no official fix, and Microsoft has not announced when a resolution will be available.<\/p>\n\n\n\n

    What Happens Next?<\/h2>\n\n\n\n

    Microsoft says it is investigating the reports and will provide an update when more information becomes available.<\/p>\n\n\n\n

    Until then, users who have not installed KB5120998 can choose to wait. Those already experiencing cursor problems can report them through Feedback Hub and monitor Microsoft’s Windows release-health page for a fix.<\/p>\n\n\n\n
