Released on Thursday, August 27, 2026, the update is causing a range of display issues. The most notable problem involves the mouse cursor, which can disappear entirely or appear incorrectly sized, either too large or too small.
New Features, Old Bugs
This update was not part of the Windows Insider program, making it accessible to anyone who manually checked for updates. It brought welcome changes, including the ability to move and resize the taskbar. Improvements to Windows Search were also part of the package, features previously exclusive to Insiders.
These advancements are being overshadowed by critical bugs. Beyond the cursor problems, users report that desktop wallpapers may disappear, reverting to a black background. Blurry fonts are another reported issue, particularly impacting high-resolution displays.
The cursor issue, in particular, renders a PC nearly unusable for many. Microsoft has formally acknowledged the problem on a support page, stating it has received reports indicating that mouse cursor personalization settings are being changed or reverted to certain standard settings
following this update and later releases.
These glitches persist even after restarting the PC, requiring users to reset wallpaper settings repeatedly.
How to Roll Back the Update
For now, the only reliable solution for affected users is to uninstall KB5120998. The process is straightforward:
- Open Settings
- Go to Windows Update
- Select Update History
- Click Uninstall and find KB5120998 in the list
Rolling back this optional update will not affect any security patches. Users report cursors returning to normal after the rollback, and wallpaper issues were tied directly to this version.
