The company suggests users need to force restart their device once they come across the black screen.

They need to press Ctrl+Alt+Deletethen select the Power button in the lower right corner of the screen and select Restart. Once rebooted, the computer should start normally without any issues.

Microsoft has confirmed that the bug affects Windows 10 version 1809, Windows 10 version 1803, and Windows 10 Enterprise LTSC 2019 on the client side, and Windows Server 2019 on the server side.

However, according to Microsoft, other client and server products are not affected.

The company is currently working on a resolution but no turnaround time has been given for the fix. Microsoft only suggests that a “small number of devices” is affected by the issue, thereby not providing clarity on the number of affected devices.

  1. I have had this bug on my Asus laptop. However ctrl-alt-delete would not work. I got to the black screen with the rotating loading animation but got stuck to this screen. I had to forced shutdown a few times until I got to the windows recovery menu. Then revert to a previous version

  2. You can’t do ctrl-alt-del or any other key combination on the black screen. Will likely have to revert to an older version through recovery.
