Somebody please HELP!

Really stuck now.
i have been running 8.1 pro for a long time now but want to upgrade to 10 using the upgrade tool just gives me the error not activated !!!

MS toolkit wont activate the damn thing i can only rearm 8.1 to keep away the activate windows message.
Looking around i cant see a iso file for windows 10 so can anyone help me out?

Im ready to smash this thing to oblivion
