hye guys, i wanna ask something, before this i'm using windows 8 pro, then i upgraded to windows 8.1 when the 8.1 version is released..but before this, i was already used the key about 3 times, because i kept formatting my pc because get some problems, the question is, i wanna buy new mobo and cpu, now i'm using amd set, i wanted to change to intel..so if i change mobo and cpu, then i do a format, can i use my current activation key again?
