10586 Update Available on x64 Home Win10, not Dev, regular via InstallTool As Of Today. Win8 OEM BIOS Key (Had to kill previous Win8, but everything that could have been done wrong, was done so: no image, no Win8 Environment Report Tool data collection(you know, to activate Win10, read too late about it.), no backup disk(Win8 would not allow to make it). After killing Win8 failed to find correct OEM image, or any Win8 that would take the stupid OEM key.) Hope that everything works.If it doesn't, I have nothing else to lose and will be forced to turn to dark side. Don't make me do this MS I want to be good, I really do...
