How to Add or Change the Manufacturer Information for your Computer

If you build your own computers, you will occasionally notice in various places that the manufacturer of your computer is listed as unknown. The system properties applet will show the information you place using this method.

Add or Change the Manufacturer Information for your Computer

1. Open the Registry editor.
   • Click Start, type regedit.exe and press ENTER
2. Navigate to the following location

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation

   Note: If the OEMInformation key is missing, you’ll need to create one manually.

3. Create string values (REG_SZ) and add matching data, as per the table below:
   

   Value name	Data	Value type
   Logo	<Path to your logo file>*	REG_SZ
   Manufacturer	<System manufacturer name>	REG_SZ
   Model	<System Model number>	REG_SZ
   SupportHours	<Support hours>	REG_SZ
   SupportPhone	<OEM Support Phone number>	REG_SZ
   SupportURL	<OEM Support URL>	REG_SZ

4. Exit Registry Editor.
5. * Note: Logo is ignored on Windows 10 Anniversary. The logo should be a 32 bit or flaked 24 bit image BMP file with the dimension of 120×120. Logos larger than 120×120 pixels are scaled to 120×120.
