How to change or add an OEM logo and information on a Microsoft Windows Vista computer?


In Windows Vista, adding support information and a company logo is not as simple as it was in Windows XP. It requires editing the Registry. Please follow these instructions.

  1. No larger than 120x120 pixels.
  2. In .BMP (bitmap) file format.
  3. File named as OEMLogo.bmp.

While this logo image file can be placed in any directory, it is recommended that it be saved it in the %systemroot%\system32 folder of your computer (for example - C:\Windows\System32). Note this path, you'll need it later.

The Registry

This section involves editing your Windows Registry.

From the Start Menu type "Regedit" and press Enter.

Navigate to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation
