Change Logon Screen Background of Windows7

Everyone would like to change the logon screen backgroundof Windows7. This will give your Windows7 a customized look. You can set your own picture as background svreen. You will have to follow the steps below to change background screen -->
1 : The image that you should set should be a .jpg file and its size should be less than 245KB.
2 : The image can have any resolution. I personally have used 1400 x 900. This is actually my screen resolution. You can use any photo editors to change resolutions. But you will have to save the image with file name backgroundDefault.jpg.
3 : Next you will have to copy the image to
C:\Windows\system32\oobe\info\backgrounds
If this path does not exist then you will have to create it.
4 : Go to Run and type regedit. This will open Registry Editor. Navigate to
HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\
LogonUI\Background

If background does not exist then right-click LogonUI, select New and then Key and name it Background. Now locate OEMBackground in the right pane. If it does not exist, then right-click Background and select New and then DWORD and name it OEMBackground.
5 : Double click on OEMBackground and set the Value Data to 1.
6 : Log off to see the new logon screen. In order to go back to old background screen set Value Data to 0.
