I turn to the Head-Fi community for computer help.
 
I am currently running Windows 7 on my laptop and I am thinking of upgrading to Windows 10 with Microsoft's offer.  My question is, will I be able to create a full system factory restore USB/Discs after the upgrade that will allow me to restore the laptop to a fresh Windows 10 if something screws up after a few months?  Do I use the Window 7 serial number on the bottom sticker of my laptop when they ask me to enter a Windows 10 serial number?
