How To Change Windows 7 Logon (Login) Background

The default logon background looks fresh if you just starting to use Windows 7. But after a while, it doesn’t look that beautiful after all.
So, you might prefer to have your own favorite ice cool background as the login background. There are two workarounds – a painful way and an easy one. We start with the hard one first.

Method 1: Registry Edit, New Folders, Files and More (pain)!

This method is very messy. It involves editing your registry create new folders and transfer your background files manually. So, it is not worth it for me to explain it here. I highly recommended you guys to skip this and move to Method 2 below. But, if you guys are still interested to know how this is done, feel free to check out this post.
Note: This method is outdated. Might not work with RTM version.

Method 2: Login Background Changer Tools

Tools are developed to save our time. Basically there are two tools out there that I can find (there might be more). Download and run it (as Administrator) and the rest are self explanatory.
