Windows 7 Logon Background Changer

Windows 7 Logon Background Changer : Customize your welcome screen wallpaper

Windows 7 Logon Background Changer is a free open source software that let you change the wallpaper of the Windows 7 logon screen (also known as "welcome screen", "login screen" or LogonUI).

It works with Windows 7 Home Basic, Home Premium, Professional, Ultimate, Enterprise and Starter, in x86 or x64 (32 or 64 bits). It also works on Windows Server 2008 R2 (but you are not supposed to customize a server).

On a side note, this small program is WPF based, it's a nice technical demo of Windows Presentation Foundation capabilities for those interested in WPF. It requires a decent GPU for the 3D animations to run smoothly.

What does it do?

- 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. Any user of the computer will then be able to change the Windows 7 logon screen wallpaper. You can also prevent users from being able to change the logon screen wallpaper if you don't want them to be able to modify it without administrator rights (option available by clicking on the "Settings" button).

- 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.

I recently discovered this program and all I can say is GENIUS purely genius. Finally someone understands the term customize. Thank you for your app. Keep up the great work.

Does this apply to Windows 7 Starter?

Est ce que vous envisagez un jour de faire une version pour Windows 8 de ce logiciel ?

Ca n'aurait pas vraiment d'intérêt, puisque Windows 8 et 8.1 supportent nativement la possibilité de changer le papier peint de l'écran de verrouillage.
