Customizing your OEM logo and system information in Windows 10 allows you to personalize your device, showcase your brand, or hide sensitive manufacturer details. Whether you want to replace the default OEM logo with your own or update manufacturer information, this guide offers clear, step-by-step instructions to do so safely and effectively. Before starting, ensure you have administrative access to your computer, and back up your system or create a restore point to prevent any data loss or issues during the process.
What You’ll Need
- Windows 10 PC with administrator privileges
- Image file for your OEM logo (preferably in BMP, PNG, or JPG format)
- Resource Hacker or similar software for editing system files
- Basic knowledge of editing system files and handling registry entries
- Backup tools or system restore point (recommended)
Step-by-Step
- Backup Your System: Before proceeding, create a system restore point or backup your current system configuration. This safeguards against potential issues if something goes wrong.
- Download Necessary Tools: Download and install Resource Hacker (or a similar resource editing tool). You can get it from its official website.
- Locate the BIOS Logo Files: OEM logos are stored within the BIOS or in system files. For Windows-based OEM info, the data is often embedded in the system registry or in specific files like “OEMInfo.ini” or embedded in system DLLs.
- Extract OEM Information Files: Use Resource Hacker to open the files located in C:\Windows\System32, such as “OEMLogo.bmp” or similar. These files may be embedded in system DLLs like “OEMLogo.dll” or “shell32.dll”.
- Edit the OEM Logo: Open the target DLL or resource file with Resource Hacker. Locate the bitmap resource representing the OEM logo. Replace it with your custom image by importing your image file (ensure it’s in the correct format and size). Save the modified file.
- Replace the Original Files: After editing, replace the original system files with your modified versions. This step may require booting into Safe Mode or using a Windows recovery environment to overwrite protected files.
- Update OEM Information in Registry: Open the Registry Editor (regedit.exe). Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation. Here, you can update fields such as Manufacturer, Model, SupportURL, and SupportPhone. Enter your custom details.
- Apply Changes and Restart: Save your registry edits and restart your computer. The new OEM logo and information should now appear during system boot or in system properties.
- Verify Changes: Check the System Information panel (msinfo32.exe) and the login screen or boot logo to confirm your custom OEM logo and information are displayed correctly.
Common Mistakes
- Editing system files without backing up can cause system instability or boot issues.
- Using incompatible image formats or sizes can result in corrupted logos or failure to display.
- Overwriting protected system files without proper permissions or in the wrong location may cause Windows to revert or crash.
- Failing to update registry entries correctly can prevent the new info from appearing or cause errors.
- Not creating a system restore point before editing can make recovery difficult if mistakes occur.
Tips
- Use high-resolution images that match the size of original logos (commonly 120×120 pixels or similar).
- Always work on copies of system files, not originals, until you confirm the process works.
- Perform modifications in Safe Mode if Windows blocks file replacements.
- Use reliable tools like Resource Hacker for editing resources safely.
- Double-check registry entries for typos or incorrect URLs, as these are easy to misconfigure.
Troubleshooting
- Changes not visible after reboot: Ensure you replaced the correct files and cleared any cached images. Restart your PC after making changes.
- System fails to boot after modification: Boot into Safe Mode or recovery environment, restore original files from backup, or perform a system restore.
- OEM logo appears corrupted or blank: Verify your image format and size. Re-edit and replace the resource with a compatible image.
- Registry changes not reflected: Double-check the registry path and entries, and ensure you saved the changes correctly.
- Permission issues when replacing files: Take ownership of system files and run your editing tools as administrator.
