Change windows Login Screen using Powershell.

Hi,
We all love customization and personalize our laptop setting. Like we all (majority of) love to change our wallpapers.

I have few scripts, which rebooted a laptop twice thrice, on those scripts i use Logon screen as a information and “how to’s” board.

and if you want some fun , you can also change the login screen with your choice of picture.
How to change login screen?

1. Make sure the picture which you want to set as Login Screen is less then 254KB
2. Rename the picture to “backgroundDefault.jpg”
3. 

Run Powershell as Administrator.

Now, we need to set “OemBackgroud” value to 1 in the registry

Set-ItemProperty -Path hklm:\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background 

 -Name OEMBackground -Value 1

Now copy the “backgroundDefault.jpg”  to the "C:\Windows\System32\oobe\info\backgrounds\" folder.

Copy-Item -Force "c:\myscripts\backgroundDefault.jpg" 

 "C:\Windows\System32\oobe\info\backgrounds\" -Verbose

Now, to test, lock you screen (Windows Key + L ) and see if logon screen is changed or not.

But mine is changed :)






How to set login screen to default again?

To set logon screen to default again, set the OEM key to “0” again.

Set-ItemProperty -Path 

hklm:\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background  

-Name OEMBackground -Value 0

I hope that you find is useful.
