Windows 7 gives you a lot of options for changing the backgrounds through their themes. Ever wonder if you could change the picture that is shown on the Windows 7 Logon ? Turns out it’s really pretty easy. All you have to do is to create a file named backgroundDefault.jpg and then copy it in to the folder
Once you have the picture out there, then you need to open up RegEdit and look for the registry hive
and then set the key OEMBackground = 1. Now lock your computer and you should see your graphic. You may have to experiment a little bit to get the right size, but that’s it. Enjoy!
