Usually, Microsoft deliver the recent updates to all widows and other Microsoft apps such as Microsoft Office, but some of these updates may interfere with installed drivers or apps, or maybe with the computer itself if the computer is very old. Although Microsoft may release a new update or patch to fix the emerged issue from previous update, it may not release fix or may delayed the release, if the is no enough reports from users about that issue.

If you think the error appears after latest windows update, try to remove it as followings:

  1. From Windows Recovery Environment or Advanced Options menu, click on Uninstall Updates option
  2. You well get two options, Uninstall Latest Quality Update, and Uninstall Latest Feature Update.
  3. Select Uninstall Latest quality update.
  4. From shown message, click on Uninstall quality update to confirm your selection.
  5. Click Done and then select Continue to boot into windows 11 or windows 10 operating system.
  6. Note: Your files will not be affected by this solution.
  7. If your issue not fixed after removing recent quality updates, back to Advanced options and select Uninstall Update option again
  8. Select Uninstall Latest Feature Update to remove the most recent feature update.
  9. If removing Latest windows update after trying both options failed to proceed or didn’t fix the issue, try another method from the next solutions.

Important Note: This process may take several minutes, so make sure your laptop is fully charged or plugged in to electric source, to avoid further system corruption in case of shutting down while this process in progress.

  6. Critical event indicates that the computer rebooted automatically due to a sever system failure.
    • Note: If there is no Critical event record, try to boot your computer or to open the app that cause auto restart many times until you see the Critical event.
  7. See what is the previous event below the Critical error that failed to start, to know what is the driver or app that led to system failure.
  8. As you will see on the video later, in my computer the Adapter driver of VMware Virtual Network is the source of blue screen error, because it is the last event executed before appearance of critical event.
    • Also, you will notice that all previous events below VMware event executed successfully.
  9. After determining the error source, open Device Manager and remove the problematic driver that you have identified as on previous step.
  10. Open Control Panel and then start Device Manager, or right click on Start icon, and then select Device Manager.
  11. Click on View panel and then select Show Hidden Devices option.
  12. Locate the problematic driver and remove it.
    • In my case, I will remove all drivers related to VMware workstation app, because it interfered with the recent windows update.

  14.  Double click on the problematic device to open Properties
  15. Navigate to Driver panel and then click on Roll Back Driver to restore previous version
  16. Select one reason for rolling back and then click on Yes to confirm your changes.
