LicenseCrawler is designed to allow you to discover application product keys and other serial numbers or licenses.
If you want to set up your computer system again, you need to have the licenses and serial numbers for all the software programs you have purchased and registered. This fact includes the Windows product key and other serial numbers for Nero, Office, VMWare, and every other application.
Instead of searching for the keys in your emails, manuals, and recipes, you could use another approach. LicenseCrawler is a sweet little application that scans the Windows Registry for Windows product keys and other serial numbers and licenses.
