I have been using windows 10 since more or less the first preview, but yesterday I format the hdd, and I installed windows 10 with a usb, now when I login with my email (the one that I used for the insider preview), windows remains inactivated.. my first question is.. Is Windows going to stop working anytime soon? (because so far I have seen that I cannot personalize it... not big deal) second question. Is there any way I can activate it as I had it before? Thanks
