A while back I wrote a post on how you can change the login screen for Windows 7, or at least the wallpaper used on the login screen. That article is still valid, but it requires you to do some registry edits which not everyone is comfortable with. I have a solution for you!
Introducing the Windows 7 Logon Background Changer. From the page:
Windows 7 Logon Background Changer is a free open source software that lets you change the wallpaper of the Windows 7 login screen (also known as "welcome screen" or "login screen"). It does not change any system file, and the program itself does not requires admin rights to run (it will just ask you to run as admin a very simple cmd file that creates the required folder and registry key with the appropriate rights) It creates a few JPEG files based on the image you want to put as wallpaper for the Windows 7 login screen, applies the appropriate cropping and sizing and saves them using the best compression quality possible.
Here is a screen shot:
Some things to keep in mind. The image you select must be a jpeg. Other formats don't seem to work so well. Also, if you happen to download it from CNET, don't just click next, next, next as you will end up with some additional junk software you don't need.
What do you think? Are you going to try it out? Know of other cool programs for customizing your Windows 7 experience? let us know in the comments!
