Product Key Finder for Windows
This portable key finder is ideal for users who are planning to reinstall their system, migrate to a new PC, or simply want to back up activation details before a system crash. The tool requires no installation, making it a convenient option for IT professionals and everyday users alike.
How Product Key Finder Works
Once launched, the utility scans your system’s registry to locate stored product keys and serial numbers. These keys are typically hidden in registry entries and are not visible to the user by default. Product Key Finder makes the process quick and easy — displaying all found license information in a clean, readable format. You can then choose to copy, save, or print the data for safekeeping.
