1. The image you need to set as the background should be a .jpg file and it’s size should not exceed 245KB.
2. The image resolution can be anything of your choice. However I prefer 1440 x 900 or 1024 x 768.You can use any of the photo editing software such as Photoshop to compress and set the resolution for your image. Once you’re done,save this image as backgroundDefault.jpg.
3. You will need to copy this image to
C:\Windows\system32\oobe\info\backgrounds
You will need to create that path if it does not already exist on your computer.
4. Now open the Registry Editor (Start -> Run -> Type regedit) and navigate to the following key
HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\
LogonUI\BackgroundIf
Background does not exist rightclick LogonUI, select New and then Key, and then name it Background. Now locate OEMBackground (listed on the right side). If it does not exist, 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. Now log-off to see the new logon screen background. If you wouldlike to revert back to the default background, just set the Value Databack to 0.
I hope you like this trick.
Just try out and give your feedback!
