Hi again, im using windows 8.1 pro with update 1, but I can´t add WMC to it, just gives this screen prntscr(dot)com/3eh4c3 Also anyone knows if that multi file check thing(I don't know how to tell, I mean, on the windows 8.1 with GA update iso, all the icons had a little check box at upper-left that you could select multiple files, I know you can this with ctrl, but I liked that way)
