Ecran qui flash lors du login Windows 11

Question

Hello

The problem is with the login which flashes 2 to 5min before displaying the option to put the user and password

This problem is on all Windows 11 machines, if the machine is on Windows 10, there is no problem, but as soon as we do a Windows 11 update and we join the machine on the domain the problem starts.

Scenario

OK Machine: Windows 10 Out of Domain and in Domain & Windows 11 Out of Domain

KO Machine: Windows 11 Updated and Domain Joined.

Troubleshooting performed:

• Updated drivers and also downgraded display drivers to lower versions

-Updated BIOS on machines

• Resolution settings

Also it should be noted that there is a GPO that assigns an image and constantly updates it across the entire domain.

Thank you

Hello，

Thank you for posting in the Microsoft Community forum.

May I know that the screen flicker phenomenon appears specifically in the boot login screen? Does your device involve remote login? 

You can try the following steps to troubleshoot the problem:

• Remote Desktop and console users experience a slow logon with a blank screen before the desktop is rendered in Windows. Longer logon times directly correspond to the number of desktop shortcuts that are defined in the user's profile.

Try to configure the login script to remove the following registry key during login: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\UFH\SHC

See the following article for more information:

• If the screen flickers while running the application, it may be caused by a display driver problem or an incompatible application. Check to see if you have any new applications installed on the Windows 11 device in the join domain.
