10 Software to Recover Product Key Licenses from Computer

There are many backup software on the market and some of them does a really good job in making sure that there is an exact copy of the important files available at the backup drive. Although backing up of files is important, many people forget to backup the Windows product key or third party software license that is installed on their computer. When their computer crashes and had to reinstall everything from scratch, they had to go through the trouble of searching for the license number to activate the software that they’ve purchased. If the license key are misplaced and forgotten, they’d have to contact the software support team and provide them with proof of purchase so that they can reissue the license.

They are stored all over the place either in a form of an external file or a registry key. Fortunately we found 10 software that can scan your computer and recover the lost or forgotten product key licenses so you can back it up in case you need to reactivate them again.
