Probably a strange question, but I'm really not 100% sure how activation works on windows 10 yet. I have several full retail keys for windows 7 and 8 that I'm going to use in the future, but may not be until after the free upgrade period is over. These are not OEM so ,from my understanding, they should be able to be moved between different computers just like retail keys could in the past. (as long as it is removed from previous computer). I just did a clean install of 10565 but have not activated it yet. Could I just go to setting>update &security>activation and then enter in each of my retail keys? Would that tie the key to my current hardware though? Since they are all retail keys, I should be able to "move" them to the new computer when the time comes right? And when the time does come, how would I activate the new computer? Would I need to enter the old windows 7/8 retail key at that point? Thanks for the help.
