OEMs usually include their logo and other information in the System information applet when pre-installing Windows. If you want to add or modify the information in the System Properties window, this article helps you do that exactly in Windows 7 and Windows Vista.
Add or Modify the OEM Logo and Information
1. Click Start, type regedit.exe and press ENTER
2. Navigate to the following location
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.
* Note: The logo should be a BMP file with the dimension of 120×120. Logos larger than 120×120 pixels are scaled to 120×120.
Sample
I’ve customized the support information page by populating it with sample entries. Here is the screenshot:

And the related registry entries.

Be sure about the bmp resolution mates.. it has to be 32 bit or flaked 24 bit image!!
One thing I found helpful for my situation is to change the support website information to the email address of the helpdesk. Just add “mailto:%20″ before the address and it will open outlook for the user to send an email to the helpdesk. An example would be to add: mailto:%20helpdesk@blahblah.com
Thanks for this guide. I have been trying to do this through sysprep but the information doesn’t show up when I’m done.
wow it is so smart thanks
its works….thank you!!!
hi i can do all this but why the pics still got pixelated?? i have use 120×120 px and is bmp format thanks
Hi !!!
Tried & succeeded at last. It only allows information like Manufacturer, Model, Support hours, Support phone & Support URl appear so do not try to create extra strings or keys as they will be useless. Seems its pre-defined. Also check out for the logo size. It should be less than 200 pixels. Thanks
