I have environment where lock screen image is embedded in user32.dll,LockWorkStation and would like to change it. Unfortunately whoever used this approach did not use change via GPO "Personalization" way and I cannot use this approach at the moment. I used PS scripting from another post Using a UWP API Namespace in PowerShell to change picture but while change is instant on win 10 it is not on win 2012R2. I can see that picture has been changed with

[Windows.System.UserProfile.LockScreen]::OriginalImageFile.AbsolutePath

but old picture is still retained.

I was playing with removal/renaming of pictures in C:\ProgramData\Microsoft\Windows\SystemData<User_Account_Security_Identifier>\ReadOnly\xxx and had mixed results.

I do not like idea of playing with permissions so question is why above script is not working in win2012R2?

  • Is your Windows fully updated including [this update](https://docs.microsoft.com/en-US/troubleshoot/windows-client/shell-experience/manage-lock-screen-image)? – harrymc Apr 26 '21 at 19:11
  • As I mentioned I cannot use GPO approach at the moment (long chain of workflow would need to be changed). – spricer Apr 26 '21 at 20:06
