Windows Update Broke Your Mouse? Here's the Fix

Microsoft’s latest optional Windows 11 update, released August 27, is causing headaches for some users. The update wipes out personalized mouse cursor settings, leaving cursors too big, too small, or completely invisible. It’s also turning wallpapers black and making text look blurry on some screens. Microsoft confirmed the cursor issue and is investigating, but for now, the only workaround is to uninstall the update.

This isn’t a mandatory update, so it’s not your fault if you installed it accidentally. It’s labeled as a “preview” update, meaning it’s a test run for bigger changes coming in September. Those changes include a resizable Start menu and a movable taskbar—features many users have been waiting for. But the bugs are overshadowing the good stuff.

If you’re affected, you’ll need to manually uninstall the update. Head to Settings > Windows Update > Update History > Uninstall updates, then find and remove “2026-08 Preview Update (KB5120998).” It’s tedious, but it’s the only fix Microsoft has offered so far. The company says it’s working on a solution and plans to roll out a corrected version by September 8.

For now, if your computer feels sluggish or your screen looks off after updating, the problem might be this glitch. Uninstalling the update could save you from staring at a blank wallpaper or an invisible cursor all day.
