Finally Microsoft has incorporated a new feature in the latest build of Windows 7 which supports the end user to change the logon screen background without using any hacks or third-party tools.
In previous version of Windows, user had to use third-parry tools like Tune-Up-Utilities to change the logon screen background easily. Windows 7 now supports customization of Windows 7 logon screen officially. Replacing the old logon screen is just another task like changing wallpaper (Desktop background). Thanks to withinwindows for finding out this excellent feature.
Follow the procedure below to change the Windows 7 logon screen.
- Fire up registry editor (Win Key + R and then type regedit, hit enter)
-
Browse to HKYE_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background , double click on key named OEMBackground and change its value to 1 (If you cannot find the path or the key go ahead and create it, remember OEMBackground is a Dword)
-
You just enabled the OEM Background functionality. Now browse to the folder %windir%system32oobeinfobackgrounds within Windows explorer. %windir% refers to your Windows install directory C:Windows in most systems. Again the folder path may not exist already, so you can go ahead and create required folders (info and backgrounds are generally not present)
Now put in any JPG file with size less than 256 kb in this folder and rename it to backgroundDefault.jpg. This file will be stretched to fit the screen, so you would want it to match the resolution of your screen so that image doesn’t look bad.
