Latest Windows 10 Update Leads To An Unresponsive Black Screen With Cursor, Here’s A Quick Workaround

Windows 10 users have been receiving buggy cumulative updates for the past few months. But if you thought that you can relax this time, Windows update problems are back again.

People who installed the latest KB4540673 update are now experiencing a new series of problems. One of the major issues reported so far is an unresponsive black screen. According to the users, they can just see a black screen without any options to boot in Safe Mode.

On top of that, they can no longer restore to a previous version. Some people took to Reddit:

“On Thursday my Windows 10 Desktop auto-updated with KB4540673. I had a black screen with a working mouse that often appeared to be loading something (it wasn’t). I couldn’t open the command prompt. Safe Mode did not work. Bios settings did not help. Also couldn’t restore from previous versions of Windows.”

So, the new update that was released to improve the Chromium Edge browser and the Expoler’s security turned out to be problematic for many users. However, if we look at the KB4540673 support page, Microsoft has only acknowledged an issue with 32-bit applications and processes.

Some affected users found a quick workaround to fix the unresponsive black screen problem. If your device isn’t booting after installing KB4540673, you can reverse the problem by following the steps mentioned below:

  1. Reboot your system and enter the Advanced Startup screen.
  2. Click Troubleshoot > Advanced Options.

The process you take around 30 minutes to remove the problematic update from your PC. Finally, restart your PC and now you should be able to normally use your computer.
