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.

Does this work with windows 8.1.

I thought I read somewhere that said it\'ll work with windows 8.

If it doesn't work with 8 or 8.1 then how come at the top of the page it says: OS: Windows 7/8/Vista/XP/200NT?

I don't understand your last sentence in your reply.

What's a Metro Control Panel?

At the top of the page there is an advertisement provided by Google Adsense. Unfortunately, there is often misleading ads displaying a fake big "Download now!" button, along with a description such as "compatible with every version of Windows" (to incite you to click).

of course, this kind of advertisement is totally unrelated to Windows 7 logon background changer. I have no control over it. And if you had clicked on it, it would have redirected you to a site containing adwares.

as for Windows 8.1, what I call the "metro-style control panel" is the new full screen control panel that is accessible by going to the full "application list" (using the little arrow located at the bottom left of the Windows 8 Start Screen), and then clicking on "Settings". There you can find the option to change the lock screen wallpaper.

No it doesn't work with Windows 8 or 8.1

Actually you don't need any 3rd party app to change the lock screen on Windows 8/8.1.

Look in the new Windows 8.1 Metro control panel, in "PC and Devices", "Lock screen" to choose your own lock screen wallpaper.

Is there a way to deploy this from a server to multiple workstations? A batch file referencing the .jpg for example?
