1. Press the win+R shortcut to open the running interface. In the above dialog box, type "regedit”; then click “OK"Open the Registry Editor, and then expand the registry. "HKEY_LOCAL_MACHINE---SOFTWARE---Microsoft---Windows---CurrentVersion--- Authentication---LogonUI---Background”; everyone will find a double-byte named "OEMBackground" Value (if not, you can create a new one), right click on the double-byte value, select the correction, and correct its value to 1 & rdquo;, as shown below.

2. Open the Windows---System32---oobe directory under the C drive, then create a folder named "info" in the directory and open it, then open the directory. Create a folder named “backgrounds”, and then adjust the background image of the JPG format prepared by itself to 1024× 768 pixels, and save the adjusted background image to the directory of “C:WindowsSystem32oobe infobackgrounds”. The file name is “backgroundDefault.jpg”. After completing the above two steps, restart the computer and you will see the effect of the repaired login interface.
Note: The background image of the edited login interface <backgroundDefault.jpg” must be controlled within 250KB; otherwise the background image of our modified login interface will not display properly!
