Windows 11 preview update resets cursor and wallpaper preferences, uninstall advised
The August 27 preview update for Windows 11 is causing mouse cursor personalization to revert to default, with some users also reporting black wallpaper and blurry fonts. Microsoft has acknowledged the issue on its known issues page. The only current remedy is to uninstall the update.
The August 27 preview update, KB5120998, is optional rather than mandatory, yet it appears prominently in Windows Update, making accidental installation easy. Beyond cursor resets, some users report the wallpaper turning black and fonts appearing blurry, though Microsoft has only formally acknowledged the cursor issue on its known issues page. The update also introduces notable features like a resizable Start menu and movable taskbar, which may explain why some users hesitate to remove it. Microsoft has until September 8, the next Patch Tuesday, to address the bugs before the final release.
This glitch could affect a wide range of Windows 11 users, particularly those who rely on customized cursors for accessibility or productivity. The temporary fix—uninstalling the update—may leave systems without the promised new features, creating a trade-off between stability and functionality. Businesses with managed fleets could face disruption if the update spreads, though the optional nature limits exposure. Microsoft's response time will likely shape user trust in future preview releases.
