Change Windows 7 “Logon” Background

There’s two types of background images.

  1. Windows Desktop Backgrounds
  2. Windows Logon Backgrounds

This script will add the required flags and permissions to the registry and create the “dummy” jpg files which are used to display the “Logon” background. This is the screen which displays the user logon details (At “Logon”).

echo OFF
set bgfolder=%windir%\system32\oobe\Info\backgrounds\

REM Creates the backgrounds folder
md %bgfolder%

REM Creates the dummy background files
FOR %%f IN (backgroundDefault.jpg background1280x960.jpg background1024x768.jpg background1600x1200.jpg background1440x900.jpg background1920x1200.jpg background1280x768.jpg background1360x768.jpg background1024x1280.jpg background960x1280.jpg background900x1440.jpg background768x1280.jpg background768x1360.jpg) DO echo 2> %bgfolder%%%f 1> NUL

REM Gives all authenticated users the right to write these files
FOR %%f IN (backgroundDefault.jpg background1280x960.jpg background1024x768.jpg background1600x1200.jpg background1440x900.jpg background1920x1200.jpg background1280x768.jpg background1360x768.jpg background1024x1280.jpg background960x1280.jpg background900x1440.jpg background768x1280.jpg background768x1360.jpg) DO icacls %bgfolder%%%f /grant *S-1-5-11:(R,W,M)

REM Forces the use of the custom background permanently
reg add HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background /v OEMBackground /t REG_DWORD /d 1 /f
reg add HKLM\SOFTWARE\Policies\Microsoft\Windows\System /v UseOEMBackground /t REG_DWORD /d 1 /f

All you then need to do is add the background image you want to this folder directory: %windir%\system32\oobe\Info\backgrounds\
