Will Microsoft removed both skip to activation when doing fresh clean install in future? Like force you to enter product key!
That's a good question. Because if free upgrade from Windows 7 Pro (Activated) with my real oem key (not from windows loader) then upgrade to free Windows 10 Pro and it activated (but no product key is given) so in future if doing fresh clean install, if microsoft removed both skip activation, then how on earth to input new product key for clean install of Windows 10 Pro? You cannot put Windows 7 Pro key on it. Maybe need to ask Microsoft about this!
I'm guessing... but valid Windows 7 or 8 keys [even OEM] MIGHT be accepted if the skip option is eliminated.
after you have successfully upgraded 7 (or 8.x) to 10, you can clean install forever. You don't need a key now, and wont need one then. The only people who will need or have keys are those hey pay for them. There is a key inputted into the install when you "Skip" entering a key, that key tells MS that you have upgraded. MS has all your hardware info, as long as you dont change too much of your hardware (especially motherboard), you will always be able to clean install Win10. Every time you clean install on that same system, MS will see the hardware ID and info that was sent during the initial upgrade, if they match you get activated. There are two keys that matter for Home and Pro (At least these two), and neither you have to have or enter, because everyone has them. I do not see them removing "skip" from entering a key. Maybe specific editions, but not the standard ones we use now. They would loose their billion user mark fast if that was the case, and we cannot have that now, can we precious?
There are no keys associated with the free upgrade and you won't be asked for one or if you are you will be able to skip it and it will activate anyway. If you buy retail you will be asked for a key of course, probably will be asked for ent too.
