CHANGE WINDOWS 7 LOG ON SCREEN

SOLUTION:-
Simple step to change the background.Follow the step below:-

• Navigate in the registry to 

HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background

• Then see if there is a DWORD value called OEMBackground and if so set the Hex value to 1.

• After you are done navigate to c:\windows\system32\oobe\ and create a info folder and then inside it create a backgrounds folder and put a JPEG file in there that is less than 256KB and call the file name backgroundDefault.jpg.

• Then reboot and done.

NOTE: If you don't have a OEMBackground key, you need to create a new DWORD, under /LoginUI/Background and once created, right-click, choose MODIFY, then set value to 1.

thank you :)
