If you want to change your Windows 7 Logon Background you would normally be advised to download a 3rd party application to do the job for you. With this Registry Tweak you don’t have to.

Remember, since this does involve editing the Registry you should take a backup before you start, but you already know that don’t you :-) If you’re new to editing the registry, start here.

1. Open RegEdit and locate

HKLM/SOFTWARE/Microsoft/Windows/CurrentVersion/Authentication/LogonUI/Background

2. In the Right Pane, Create a new DWORD and name it OEMBackground

3. Set the Value to 1 to enabled it (0 = disable)

4. Close RegEdit

Before you Reboot you need to create your background image and place it in the right folder. There are some strict rules, so pay attention please.

• Image must be placed in the folder: C:\Windows\System32\oobe\info\Backgrounds
• Images must be 24-bit and not larger than 256kb
• Default Image must be named: BackgroundDefault.jpg (This file Have to be there no matter what)
• If you would like to save resolution dependent versions of your image you can name them like this:
  • background768x1280.jpg
  • background768x1360.jpg
  • background900x1440.jpg
  • background960x1280.jpg
  • background1024x1280.jpg
  • background1280x1024.jpg
  • background1024x768.jpg
  • background1280x960.jpg
  • background1600x1200.jpg
  • background1440x900.jpg
  • background1920x1200.jpg
  • background1280x768.jpg
  • background1360x768.jpg
