Free Windows & Software Product Key Recovery Tool
SterJo KeyFinder (also known as a productkey finder) helps you recover keys quickly and safely.
Lost your Windows product key or an Office product key? SterJo Key Finder is a free, lightweight Windows utility that quickly locates and recovers product and serial keys stored on your system — including local and external drives. No installation is required for the portable build.
Fast, portable productkey recovery
SterJo Key Finder scans your Windows registry and application metadata to locate saved product keys for Windows, Microsoft Office and hundreds of popular programs. It is designed for speed and simplicity: run the tool, wait a few seconds while it scans, then save the results as a text file for safe keeping. The recovered keys can help you reinstall software or preserve license details before formatting or hardware changes.
It also can help you find Windows 10 product keys (including use as a Win 10 product key finder), recover older Windows XP keys and Windows XP license keys, locate serial keys such as a CS5 serial number, Camtasia license, VMware Workstation key, and assist with Microsoft product activation and license key recovery
How SterJo Key Finder works
Simply download the tool, run it as administrator, and it scans your system, BIOS, and external drives to locate all recoverable product keys. Export results in TXT, CSV, or HTML for safekeeping.
Example: SterJo Key Finder lists installed products and their serial keys
After launching the program, SterJo Key Finder reads registry locations and known storage formats to retrieve product keys previously present on the machine. It does not generate or brute-force keys — only keys that were actually stored on the scanned system will be shown. Use the Save option to export the recovered keys as a plain text file for backup.

Frequently Asked Questions
Is SterJo Key Finder safe to use?
Yes. SterJo Key Finder reads system registry data and displays stored license keys — it does not upload keys to external servers by default. Always download from the official SterJo site and scan installers with your antivirus if you have concerns.
Can I run SterJo Key Finder from a USB stick?
Yes. The portable build is available and runs without installation. It is ideal for technicians and recovery tasks on multiple machines.
What if SterJo Key Finder doesn't show my application's key?
Some applications store keys in proprietary formats or remote activation servers; in those cases the key may not be recoverable. Check our supported list page for compatibility notes or contact support via Contact.
Can I recover keys from a drive that won't boot?
Yes. Attach the drive to a working PC and use the "Recover keys from external drive" option. See the instructions above for the required Windows folder path.
Can SterJo Key Finder recover keys for all software installed on my PC?
SterJo Key Finder attempts to read product keys stored in the Windows registry and known formats, but it can't recover every product key. Some software stores activation information in proprietary or encrypted locations, or uses online activation services, so the key may not be recoverable.

No. SterJo Key Finder only retrieves keys that were previously stored on your system. It does not generate new or valid keys for software you have never installed.
