Top Free OEM Info Editor Tools to Download Every Windows computer comes with a system information panel that displays details about your hardware and operating system. Brand-name PCs from manufacturers like Dell, HP, or Lenovo also include custom OEM (Original Equipment Manufacturer) information. This usually features the company logo, support website links, phone numbers, and specific model names.
If you built your own PC, or if you want to personalize a pre-built system, you can easily change this data. Modifying these details manually requires digging into the Windows Registry, which can be risky. Fortunately, several free, lightweight tools allow you to safely customize this information through a simple visual interface.

Regardless of the tool you choose to download, Windows enforces a few strict rules for displaying OEM data:
Administrator Rights: You must right-click your chosen tool and select Run as Administrator. Windows will block changes to these system settings without elevated permissions.
Logo Format: System logos must be in .BMP (Bitmap) format. Standard .PNG or .JPG files will not display correctly in the system window.
Logo Dimensions: For the best visual results, your custom logo should be exactly 120 x 120 pixels. Windows will automatically stretch or compress images that do not match these dimensions. Where to See Your Changes
Once you apply your changes using any of the tools above, you can instantly view your handiwork:
Press the Windows Key + Pause/Break on your keyboard, or open the Settings app. Navigate to System and click on About.
Scroll down to the support or system specifications section to see your custom logo, brand name, and support links.
Using these free tools is an excellent way for system builders to add a professional touch to custom PCs, or for everyday users to add a bit of personal flair to their daily machines.
