WindowsKeyFinder

WindowsKeyFinder is a tiny utility that enables you to find and decrypt the Windows key so that you can move it to a new machine. The utility is as simple as it gets and all you need to do is launch it to grab the key, an operation that will take just a few seconds. Once it is done, the tool displays the license and you can copy it to use it for another machine.

It is worth mentioning that the program does not work with any type of licenses, as during our testing it couldn’t grab an OEM license. If you got an OEM license, then   learning it is a simple matter of finding the sticker located somewhere on your hardware. If the sticker was damaged or destroyed, then it may cause some complications especially if you want to reinstall windows. Nevertheless, you can still retrieve it via Command Line.

The tool seems suitable for older editions of Windows where you needed to find the physical DVD or documentation to get the 25-digit alphanumeric code. If you are attempting to install an older version Windows on a new machine for which you want to use a previously owned license that you are currently unable to find.
