Windows Server 2022 Faulting Module twinui.pcshell.dll

Question

Hi all,

After some recent Windows Server Updates I am unable to use one of our servers. When logging on the screen just flashes (with any domain admin level or higher account). Local admin account seems to work, but does not have access to install modules via PowerShell (even running as admin...?). The error I have been able to get from the event logs is this:

Faulting application name: explorer.exe, version: 10.0.20348.1487, time stamp: 0x1c1c7563

Faulting module name: twinui.pcshell.dll, version: 10.0.20348.740, time stamp: 0xa41f4220

I am also unable to access the Control Panel, Windows Settings or the start menu. Currently I can't restart the server cleanly either..

Answer 4

I tried everything I could, even removed the update using PowerShell to no avail. I have had to restore the server from a two week old backup from before the update was installed...

Thanks all
