I use Windows strictly as a gaming platform in Boot Camp on my iMac. I was planning of using the Insider Program to get Windows 10 preview going forward, been using it since about 2 month. Today I kind of got screwed, because I decided to do a clean install of the final build thinking that my preview license would still work if I still subscribed to the Insider program in Windows 10. And now I've just learn that by doing a clean install with the final build I have lost any way of activating a preview copy of Windows 10 forever from the insider program. (normally with a simple update install it would have worked normally). Anyway, now I'm considering my option. And i'm thinking to myself : Well, what happen if I don't activate Windows 10 ? I know that Windows 7 had a notification system that was designed to be annoying after 30 days, also I understand that there are some personalization and options that aren't available. But it was a while ago, and I can't find any useful information on the Windows website (honestly, Microsoft websites for their products are such a mess...) So, anyone have any information ?
