The problem with license keys is that they are not always visible once they have been used to activate the license. If the license key is misplaced, you must contact the software support team and provide proof of purchase to reissue the license. To activate Windows or paid software, you require a valid key, which needs to be entered either during installation or after installing the Windows/software.

This creates significant issues when the computer crashes and you need to reinstall everything from scratch. If you have forgotten to back up the license key for the Windows operating system or another paid app, it’s time to scan your Windows registry and recover all the product keys.īacking up the Windows product key or third-party software license installed on your computer is often forgotten. In essence, all of these applications scan the Windows registry to produce the license key.

However, many of these applications do not work as advertised. There are numerous free applications available in the market that claim to recover product key licenses from a computer.
