The Tweaks.com Logon Changer for Windows 7 provides an easy way to customize the logon screen background with just a few clicks. Simply download the free application, run it and click Change Logon Screen.
Fast and easy to use. Does what it's supposed to do.
None that I've found.
The moment I saw the Windows 7 logon screen, I knew I wanted to change it. This program allows me to do that with no muss and no fuss. One reviewer stated that this program has a hidden fee somewhere in it. If that's true, it's so well hidden that it has never come into play. And I have used the program several times. Another reviewer complained about the 245K file size limit. That file size limit is imposed by Windows, not by this program. If you design your screen with a limited color palette and simple design it will compress to a smaller size with better quality. Keeping it simple doesn't mean you can't make it elegant. Use your imagination.
You are limited in the file size of the picture that you use for the log in screen which makes for a poor quality 1680x1050.
I use it so it feels like my computer is MY computer. I would suggest any body that wants this type of feature should use this program. It's easier to use than the stardock log on changer but not by much.
