When reinstalling an operating system you have to search around for all the product keys for your software; a neat way to get it all in once place is with the License Crawler tool. Instead of manually searching through CD cases, emails, and instruction manuals for those keys, License Crawler searches the registry looking for anything that could be a product key. Any keys that are registered in there should be found, including the Windows key and keys for programs like Office, Nero, and VMWare.
License Crawler finds keys pretty quickly, my computer has a lot of programs installed and it finished searching in 1-2 minutes. All Windows versions from 95 to 7 are supported. License Crawler is totally free, small and very portable. It doesn’t require an installation and it can scan a remote hard drive.
