does windows get the product key automatically

I am using sony vaio notebook, if I upgrade using usb media does windows automatically fetch product key from recovery partition

If your notebook came with Windows 8.0 pre-installed, then it will fetch the product key from the motherboard. I you have an older PC, then it will ask for your windows 7 product key that is located on your sticker. A new windows 10 key should work too.
