How to Use CT OEM Logo Changer The CT OEM Logo Changer is a lightweight, portable utility designed to customize the System Information screen in Windows. It allows you to replace the default manufacturer logo with any image of your choice and edit system information strings like the manufacturer name, model, support hours, and website.
Follow this guide to safely modify your Windows System properties using this tool. Step 1: Prepare Your Custom Logo Image
Before launching the software, you must format your custom image correctly to ensure Windows displays it without distortion. Format: Save your image as a 24-bit Bitmap (.bmp) file. Dimensions: Resize the image to exactly 120 x 120 pixels.
Transparency: Standard Windows BMP files do not support transparency; use a background color that matches your system’s light or dark mode theme. Step 2: Download and Launch the Tool
Because the tool modifies registry entries, it requires administrative privileges to function. Download the tool from a trusted source. Extract the contents if it arrives in a .zip archive. Right-click CT OEM Logo Changer.exe. Select Run as administrator. Step 3: Input Your Custom System Information
Once open, the application displays a simple interface with several text fields. Fill these in to customize your system properties.
Manufacturer: Enter your name, brand, or custom organization. Model: Type a custom model name for your computer.
Support Phone / Hours: Add custom text or contact information.
Support Website: Enter a valid URL (e.g., your personal portfolio or business site). Step 4: Apply Your Custom Logo Link your prepared .bmp image to the utility.
Click the Browse or Load Image button next to the logo preview box.
Navigate to the folder containing your 120×120 pixel .bmp file. Select the image and click Open.

If your logo does not appear or looks pixelated, keep these troubleshooting tips in mind:
Image Sizes: Windows will reject or distort images that are significantly larger than 120×120 pixels.
Permissions Error: If the changes do not save, close the app and reopen it specifically using the “Run as administrator” option.
Reverting to Default: Click the Clear or Restore Defaults button within the app to wipe the custom entries and return to the factory Windows configuration. To help me tailor this guide further, let me know: Which version of Windows (Windows 10 or 11) are you using?
