Windows Product Key Scanner

System Requirements

This tool works on any version of Windows, starting from Windows XP, and up to Windows 10. Both 32-bit and 64-bit systems are supported.

Known Limitations

  • If you purchased a computer from a large company, the product key displayed by this tool might be different from the product key you see on the sticker. It happens because the company uses the same duplicated disk with the same product key on all computers of the same model.
  • You might see the same product key multiple times, simply because it's stored in multiple locations or because the key was found with multiple scan methods (Registry, BIOS, WMI).
  • This tool can find your product key only if it's stored on your systems. For some license types, the product key is not stored in the Registry at all.
