MajorGeeks Windows Product Key Recovery is a simple VBS script to retrieve your Windows product key.
While there are numerous tools to retrieve your product ID, we wanted something simple that required no installation.
Merely extract MajorGeeks "Windows Product Key Recovery.vbs," double-click it and if your Windows key is where expected, a window should pop up with your product key. Write it down, and you can delete "Windows Product Key Recovery.vbs" and MajorGeeks Windows Product Key Recovery.zip if finished.
MajorGeeks Windows Product Key Recovery was tested on Windows 10 and should work through Windows 7.
