Screen flickers on Windows 2012 and Windows 2016 servers after installing Citrix components

Problem Description: After you install Citrix components on Windows Server 2012/ 2016, the screen starts flickering. If you log in with the domain account you will be presented with the blank screen. If you log in with the local admin account, then you can see the desktop but it keeps on flickering continuously.  The server keeps on crashing explorer.exe continuously so you cannot open any program on it.

Solution:  Restart Windows server in Safe Mode and log in with the local admin account. Open registry editor and create registry keys with following details.

Keys :



Value Name: ExcludedImageNames

Type: REG_SZ

Value: explorer.exe

If registry key(s) already exists, then just add explorer.exe to the vale by adding a comma.

Example process1.exe,explorer.exe,process2.exe

Reboot the server for changes to be effective.
