Change / Hack Windows 7 Logon Screen Background

Have you ever wanted to change that default blue login background for Windows 7? Well, now you can.

WARNING: this hack requires editing your computer's registry and should be done very carefully. Messing up your registry can mess up your whole system.

> Open the Registry Editor by typing "regedit" into the Start Menu search box


> In the Registry Editor, navigate to the following key:

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



>>If Background does not exist right-click LogonUI, select New and then Key, and then name it Background.


>Now locate OEMBackground listed on the right panel.

>> If OEMBackground does not exist, right-click Background and select New and then DWORD and name it OEMBackground.


> Right-click on OEMBackground and select Modify... Set the Value Data to 1.


Congrats you have successfully edited the registry! Now...

> Select the image you would like to set as you new background. The image should be a .jpg file and it's size should not exceed 245KB. I prefer to keep the images at 1280x1024, but supposedly you can use any size. There are some samples posted below. You can use any of the photo editing software, such as Gimp, to compress and set the resolution for your own image. Once you're done, save this image as backgroundDefault.jpg .

SAMPLE Login Screen Backgrounds




Remeber to rename these backgroundDefault.jpg if you download them

> You will need to copy backgroundDefault.jpg image to:

C:\Windows\system32\oobe\info\backgrounds


>Get there by copying and pasting the address into your window bar


>> If this path does not exist, you will need to create it folder by folder.



Once you have the image successfully copied into the correct path, log off and you should see it. 

If you would like to revert back to the default background, just navigate back to OEMBackground and set the Value Data back to 0.
