Foresee or predictions? Is it too easy to free upgrade or pivate upgrade? Maybe this is the marketing strategy! I guess MS will "control" all the win10 one yr or later when the market share of win10 is over 60% cos at that time u can not roll back to win7 8. If u use win7 or 8, u can switch it off. Then, MS can do nothing even tho it is pivate or hactivated by KMS. But Win10 update can not be switched off, MS maybe use the updates to check your OS is pivate or not, then make a notice that u pay it or lock it! This is my feeling about it. Hope that it is not true.
