Hello. I’m trying to find out how to change the background to the login screen of my Dell Studio 1558 running Windows 7 Home Premium 64-bit. Unfortunately I haven’t had that much success in doing so, after reading a tutorial online that told me to change the value in some registry files, and rename some files in the System 32 directory. While I specifically adhered to those instructions perfectly, it still did not change the background to the login screen as planned. Help would be much appreciated. Thank you very much.
