How many times have you felt the need to recover license key of your Windows Operating System? You must have experienced this sometime, either while reinstalling your computer system or when activating/upgrading your Operating System. If you have purchased and using a genuine license of Windows OS it is very important that you take a backup of your license key and store it in a safe place on external media or backup to a cloud storage.
We have shown you free applications to backup and recover license key for applications on your Windows computer and also to recover license key for Windows 7/Windows 8 and MS Office. The small utility we are going to discuss here does only one job and does it pretty well. Windows Product Key Finder can find and recover license key for all version of Windows OS very easily.
This small utility runs without installation so it gets a big thumbs up from us. The only requirement to run this software application is .Net 2.0 (which is installed by default on Windows 7 and Windows 8).
