Re: Consumer refers to who's paying

You are confused. If you buy a computer from an OEM or retail and it has Windows installed then part of the price that you pay goes to Microsoft for the Windows licence. It may be bundled so that you don't see this component of the cost, but it is not free in any sense.
Certainly, if you had already paid for Windows 7 or 8.1, then Microsoft had, for a limited time, allow an upgrade to 10, but that was not free, it was just part of the price that you paid for the earlier version.
There have been versions of Windows that were free (of cost) such as 'Windows with Bing', and 'Windows 10S' may be free of cost (to the OEM) but these require the user paying Microsoft if they are to overcome the limitations, or if they want any useful software which they must buy from the store.
