LogonStudio 1.5 was released not too long ago, and many people have been asking if they can change their Windows 7 logon screens with it. The answer is yes, but right now Windows 7 support is only provisional, so it is possible you may encounter an issue, but overall it has been performing extremely well
First, add LogonStudio to your Impulse account, and download it from there. This way you will have the latest version available.

Oh, did I mention it’s free?
Once you have it installed it’s very easy to use. You can jump right in and use one of the included logons, or download one of thousands available at WinCustomize.com. Just select which logon to use, hit apply, and it’s done!
A new feature is the ability to easily use your current desktop wallpaper as a logon. It’s also easy to get back to the Windows default logon if necessary.
If you have an image you would like to use as a logon, you can create your own just by dragging the image into the LogonStudio window. You can even save it to share with others.
LogonStudio also works on Windows Vista, so be sure to give it a try!
