No. It used to be that you got a “restore disk” with your new computer. I’ve had a few dells that had this, Apple used to as well. Now if anything, there is a rescue partition or a utility that knows how to download an rescue image. Without a valid license key you shouldn’t be able to use the restore disk. A lot of people who got these just threw them away. This guy was trying to help them reset their computer to a good state. In this case Microsoft would prefer you buy a new license, but these people already have one (usually on a sticker on the computer somewhere).
