Logon screen’s can be changed very easily on your windows 7 PC.
Logon’s make your system look cool plus many theme’s come’s with a matching logon screen.
So here’s a short tutorial on how to change it on windows 7:
1.Enabling Custom Backgrounds
This feature is disabled by default, so you’ll have to enable it from the Registry Editor. You can also use the Group Policy Editor if you have a Professional version of Windows – scroll down a bit for the Group Policy Editor method.
Launch the Registry Editor by typing regedit into the search box in the Start menu and pressing Enter.
In the Registry Editor, navigate to the following key:
You’ll see a DWORD value named OEMBackground. If you don’t see it, right-click in the right pane, point to the New submenu and create a new DWORD value with this name.
Double-click the OEMBackground value and set its value to 1.
2.Locating backgrounds folder
Open Windows Explorer and go to the following path:
If you found a folder named Info and inside it backgrounds, this step ends for you.If you can’t find then create a new folder Info in oobe and inside Info folder create another folder named backgrounds.
3.Setting the desired image as Logon
Rename your desired wallpaper as backgroundDefault.jpg and place it inside the folder backgrounds (images must be less than 245KB in size).
Done! Enjoy the logon , to check it out press Win+L.
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 Logon Editor by Vincent Bethmann.
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. This also lets you quickly change your logon wallpaper back to the Windows 7 default.
