Same issue here. I have a Dell Gamer 7559, with 16GB, GTX960M, SSD, M2 and i7-6700hq. It runs most apps and games fine!
I really don't understand why I can't upgrade to 11. I see "new" laptops/notebooks with lower specs running 11.... it just doesn't make any sense...
Also I don't want any workarounds... I just want to install it officially...
Please MS! do your "magic thing" or whatever... and make it work...
