How to Add OEM Info in Windows 11

You can add OEM info in Windows 11 in order to make it show a vendor logo, its name, and other details on the System > About page in Settings. It also appears in the classic System Properties.

Microsoft allows manufacturers to place OEM information into the About section in Windows Settings. Users can find there detailed information about a particular model, a link to the manufacturer's website, support hours, support phone, etc. If you own a PC building show and want to add a bit of personalization to your PC, this article will tell you how to add OEM info in Windows 11.

Similar to all hidden things in Windows, it all begins with opening Registry Editor.

Add OEM Info in Windows 11

1. Press Win + R and enter the regedit command. There are other ways to open Registry Editor in Windows 11, which we have covered in a dedicated article.
2. Go to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation. You can copy that path and paste it into the address bar.
3. Now it is time to create a few string (REG_SZ) registry values with all the data you need. Right-click empty space and select New > String.
4. Create one or several of the listed below keys and change their values accordingly.

Supported values

Here is all the info you can include in the About section:

• Manufacturer. Vendor of a PC. For example, MSI, ASUS, Microsoft.
• Model. For example, Laptop 2, Desktop 4, Tablet S, etc.
• SupportHours. Here you can put a time when you or your shop is available for support inquires.
• SupportPhone. Again, straightforward. Specify a phone a customer can use to reach you for support.

• Logo. Apart from text OEM info, you can put your own logo in the About  Keep in mind there are some limitations. You can only use a 120x120 pixels BMP file with 32-bit color depth. Place a file somewhere in the OS's directories and then copy the path to it. Use it as the Logo value  data.
