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.

Hi !

A little over a year ago, I downloaded & used very succesfully your background changer.
I used one of my photos full screen, beautiful. NOW I tried to change the photo, all works fine EXCEPT that there is right in the middle of the photo that awfull square with that scilly yellow fower AND my name-spelled in French while my comupter is in English.

It looked a million times better when there was the photo only.
Is there a way to revert to the \"old\" system?? I\'m VERY disappointed.

Thank you in advance for your help.

Stephen Collingwood

P.S. Don't you expect to find more than one person in the world with a particular name ???

I'm not sure to understand what you mean.

The last time I updated this app was more than 2 years ago. If you used it last year, then it's the same app you've been using today.

The user account picture has always been in the middle of the logon screen. That is not new.

Maybe you did use another logon changer app last year and you confused it with mine? Some "logon changer" appps may allow to change the layout of the logon screen.

Can I randomize or otherwise automatically change the logon screen at each boot?
