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 downloaded this directly from your website, scanned for viruses, and got a negative detection. Then I ran the program which downloaded an installer that tried to install several spamware programs like registry optimizer, and search dialer and a bunch of crap. NO THANKS

I'm sorry to read about your terrible experience, but I can assure you that there is no adware/crapware bundled with my apps.

the actual download link for Win7 Logon Background Changer is:

but I think you have clicked on one of those fake "DOWNLOAD NOW" buttons the appears in advertisements served by Google Adsense on my site, and you ended up downloading something not related to my app. Unfortunately I have no control over these misleading ads. I tried to ban them in my Google Adsense settings, but they keep coming back under new domain names.

This program is awesome!

There is actually an another way of Fixing that Write-Error:

1.go to the Background Folder
2.open properties and go to user
3.go to the tab "Security" and click Edit
4.then go to Add and type your current Username in.
5.After that you just have to make a (X) at Full Control.

And there u go! :)
