How to retrieve Win product key from uefi using the command prompt

From many years, pc manufacturers don't use the label of Windows Product key anymore. This because UEFI bios has the possibility to store and protect that key. This is a really limitation for an user who wants to restore the pc without having the recovery cd created soon after the first setup. To partially overcome this problem, Microsoft gives you the possibility to retrieve the product key using the command prompt. Here, the way to get it: 1) run the command prompt with administrative privileges 2) type the command:

wmic path SoftwareLicensingService get OA3xOriginalProductKey
