The following will show you how to customize the Windows 7 (and Windows Vista) OEM information to display information more specific to your environment. You’ll be able to add information like Manufacturer information, Support hours, Support phone number, and a Support website. (Oh yea, and add a custom logo image.)
The first thing you want to do (assuming you want to have your own logo image) is to create a 120 pixel by 120 pixel 24-bit bitmap image file. You’ll then need to place this file somewhere on the the local disk of the PC. I suggest creating a folder called OEM under the System32 folder and placing the image there with the name of OEMLogo.bmp. (C:WindowsSystem32OEM)
Now you need to open up the registry editor and go to HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionOEMInformation.
To add your custom logo, go tothe OEMInformation key create a new Reg_Z string value and name it Logo and give it a value of the path to the folder in which you put your image file.
To add a manufacturer name, create a Reg_Z string and name it Manufacturer and give it a value of whatever you would like the manufacturer to be.
To add support hours, create a Reg_Z string and name it SupportHours and give it a value of whatever you want your support hours to be.
To add a support phone number, create a Reg_Z string and name it SupportPhone and give it a value of whatever you want your support number to be.
To add a support website, create a Reg_Z string and name it SupportURL and give it a value of whatever your website is.
Look at the example image below if you’re not getting anywhere with the instructions above.
Here’s a quick registry import to.
