windows 7 - Stardock's LogonStudio doesn't change the login screen background?

I am using a Sony VAIO laptop (that comes with a custom login screen to begin with) running Windows 7 Home Premium 32 bit.

I am trying to use Stardock's LogonStudio to change the background of my login screen.

I can add new images to the program, but no matter what I use (preloaded or my own images), it never manages to change the login screen background.

Is there a way I can get this to work?

Answer

I have a VAIO as well and it looks like getting this to work requires a small registry edit:

1. Go to Start->Run and type in regedit.


2. Back up your registry using File->Export.



3. In the tree on the left, navigate to the following key:

   
   

   HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background




4. Double-click on the OEMBackground key and change its value to 0.



5. Click OK.

The logon screen background should now change as expected.
