Windows 10 update causing blue screens of death — what to do

Some Windows users are reporting major problems with this week’s Windows 10 security update, while others are unable to install it at all.

Since the update, KB5001330 for Windows 10 versions 20H2/2004, addresses five zero-day bugs and patches several notable remote-code-execution vulnerabilities, it’s a big deal.

However, after the patch was released on Tuesday, users started complaining on various Internet forums that KB5001330 failed to install, resulting in issues such as never-ending boot loops and the dreaded Blue Screen of Death (BSOD).

On the Windows 10 subreddit, one user wrote, “I modified and am stuck in a bsod loop.” Another user replied, “Same thing happened to me with KB5001330 on W10 Home 20H2 x64.” “I was able to boot after restarting with ‘Disable driver signature compliance.'”

Some users who have successfully installed the update have reported experiencing sudden drops in game output, including graphical stuttering and unpredictable FPS drops, on the Windows 10 subreddit.

What to do if you’re having problems with the Windows 10 update KB5001330

If you’re worried that the new Windows 10 update will break your computer, the only thing you can do is wait until Microsoft fixes the problems. Given the seriousness of the security vulnerabilities addressed by this patch, we can only hope that the OS creator responds quickly.

If you’ve already installed the patch and can open Windows but are still having issues, the safest way is to uninstall it and reboot your computer. Here’s how to do it step by step:

  • Launch the Windows 10 Settings app, easily found by opening the Start menu and typing “Settings”
  • Click “Update & Security”
  • Select “Windows Update” and hit “View update history”
  • Click “Uninstall updates” and select “Security Update for Microsoft Windows (KB5001330)”, then confirm when Windows asks if you’re sure
  • Reboot your PC

If you’ve already applied the patch and your machine is still stuck in a boot loop, preventing you from opening Windows, you’ll need to take more drastic steps.

As previously stated, some users have reportedly been able to get out of the loop by disabling driver signature compliance, which can be done by selecting Advanced Startup during the Windows 10 boot series, pressing the Troubleshoot button, then navigating to Advanced options and disabling driver signature enforcement in the Startup Settings.

It’s still uncertain how widespread the problems caused by this update are, but this isn’t the first time Microsoft has released a Windows patch that has caused significant problems for users. Given the seriousness of the security vulnerabilities addressed by the KB5001330 updates, we can only hope that Microsoft resolves these issues quickly.
