How to Scan your PC for Software Licenses

Missing your License Key for a Windows Application?

We have all had situations where we are missing a license key for a software application we have installed on our PC.

When you try to find the product packaging or email that contains the missing key, you can never find them!

So it would make sense to scan your PC to see if you can locate them?

The only problem is where do you look and how do you extract the information?

Software creators often store the license keys in the Windows Registry, and some such as Adobe even use a special file called an SQLite database.

Scanning the Registry?

You can manually search through the registry if you wish!

But a faster method is to use a special utility like the one from Martin Klinzmann called License Crawler:

(The utility also has support for searching SQLite too.)

After downloading (use the FREEWareFiles link on the download page) and extracting from the ZIP file, you can then run the program from the folder – no need to actually install it.

License Crawler can discover application product keys and other serial numbers or licenses very quickly and supports all versions of Windows operating system from Windows 95 to Windows 7.

You can also export the information as a .txt file by going to the File menu in the top left hand corner.

This is a handy utility for quickly scanning your computer for software licenses.

As it does not need to be installed on your computer, it can easily be stored on a USB memory key.
