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?
