Hi, Have decided to upgrade to the free windows 10 from windows7, have ssd for windows 7 and 1tb for programes/games ect. Is it possible to have a dual boot system for windows 7/10 and keeping both activated for updates. Or wiil upgading to windows 10 mean that i loose the liceince for windows 7. If any one has allready done this is there any problems running 2 os systems on on computer.
