hey guys wanted to ask microsoft offers free windows 10 but you will later need product key coz many features wont work such as changing background and other things. but this free version is missing few things such as on windows update? or they both same to the real windows 10. I mean does it make any difference? i want to know what i will be missing with trial version no key activated vs activated version of windows. Especially for gaming if any changes or stops me from gaming. Recently ive been having problem with GTA 5 im thinking its coz of the trial version windows 10 that came with my pc when bought 2 week ago no key activated and few windows updates stopped or failed and now dont show up.
