Windows 11

Windows 11 users updating to the May 2022 update reported BSOD errors, which was later confirmed by the Sophos antivirus team.

While Microsoft is yet to acknowledge this, Sophos teams said it’s due to the incompatibility issues between the system drivers and the latest May 2022 update. Sophos recommended rolling back the update until Microsoft comes with a fix.

Windows 11 BSOD Issues After Cumulative Updates

The Blue Screen of Death (BSOD) is a nightmare for many. Though knowing the exact issues can let users fix them, it’s often triggered for various issues and shows no reasons. One such issue is now bothering Windows 11 users, who updated their systems to the May 2022 update.

This is a cumulative update containing security fixes for issues reported in previous updates, thus it’s mandatory. Yet, it’s causing even more issues now. The May 2022 update for Windows 10 users too has some issues reported, including the failure of opening some apps.

And now, Windows 11 users report BSOD screens after upgrading to the KB5013943 update. This was confirmed by Sophos, an antivirus software who’s one of the victims of this issue. The company said that Windows 11 latest update is causing incompatibility issues with its drivers, thus triggering BSOD.

Some mentioned seeing the error codes like “APC_INDEX_MISMATCH” is not just on their primary machines, but also on secondary machines like the VMs. While Microsoft is yet to acknowledge this issue, Sophos recommended rolling and uninstalling the update, and mentioned how;

Pause Windows updates to prevent the update from installing.

  1. Select Start > Settings > Windows Update.
  2. Pause updates for 7 days.
  3. Open Control Panel.
  4. Click Programs And Features.
  5. Click View installed updates.
  6. Look for KB5013943 and Uninstall it.

This may leave you vulnerable to the previously reported security issues, but thwarting them with caution is better than being stuck at a BSOD screen.
