1. The image you need to set as the background should be a . Jpg file and the size must not exceed 245KB .
2. The image resolution can be anything of your choice . But I prefer 1440 x 900 or 1024 x 768. You can set one of the photo editing software like Photoshop to compress and resolution for your image . When you're done , save this image as backgroundDefault.jpg .
3. You must copy this image to
C : \ Windows \ system32 \ oobe \ info \ backgrounds
You need that path if it does not already exist on your computer .
4. Open the Registry Editor (Start - > Run - > type regedit ) and navigate to the following key
HKLM \ Software \ Microsoft \ Windows \ CurrentVersion \ Authentication \
LogonUI \ Background
If Background does not exist rightclick LogonUI , select New and then Key, and name it background . Now find 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 OEMBackground and set the value to 1 .
6. Now to see. Log-off of the new logon screen background To return to the default background , but put back the value data to 0. That's it you have successfully changed your logon screen background,
