Whether it’s just for fun or your company wants to brand their Windows 7 logon background, here’s how:
Prepare the system:
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background" /v "OEMBackground" /t REG_DWORD /d "0x1" /f mkdir c:\windows\system32\oobe\info\backgrounds
Now, at least place the following file in c:\windows\system32\oobe\info\backgrounds.
- backgroundDefault.jpg
This will be the “fallback” image, so if none of the following files is found the image above will be stretched to fit your current resolution.
Optionally you can place the following files:
- background768×1280.jpg
- background900×1440.jpg
- background960×1280.jpg
- background1024×1280.jpg
- background1280×1024.jpg
- background1024×768.jpg
- background1280×960.jpg
- background1600×1200.jpg
- background1440×900.jpg
- background1920×1200.jpg
- background1280×768.jpg
- background1360×768.jpg
Remeber: file size cannot exceed 256 KB (so i’ve heard, not tested)….
