Third-party software | How to Change the Logon Screen on Windows 7

If you are uncomfortable with manually tinkering with the registry -- or simply have better things to be doing with your time -- we understand. Various third-party applications can change Windows 7's default logon wallpaper, but our personal favorite is Tweak.com's Logon Changer.

The software is ridiculously easy to use, doesn't require installation, and it even has built-in tools to automatically resize and recompress your images while leaving the original file untouched. The Logon Changer also lets you quickly change your logon wallpaper back to the Windows 7 default.

Start by downloading the app here, and then unzip the executable. Run the program and it should present you with a preview of your logon screen along with a few self-explanatory options: "Change Logon Screen" lets you browse to a new image, "Test" will bring up your logon screen, "Revert to Default Logon Screen" reapplies Windows 7's original wallpaper.
