I dual boot Ubuntu 14.04 & W7-64 bit.
IE is crap,always has been IMHO.
I have often railed against W8,8.1 & W10.
It's been obvious for years,at least since W8,that M$ were moving along the MAC route,so that they 'own' users, make them use their own version of Apple Store & then raise prices at their leisure.
I will NEVER downgrade W7 64 bit for any newer version of Windows.
There's so many browsers available for the internet(IE blocks many D\Loads-Firefox doesn't),there's WINE API for gaming,or use STEAM.
I'm not aware of using DX12 in W7,even on a VM?
If using WINDOWS, just switch off Event Viewer Logs that are sent to M$,of course there is a minimal chance of thing's not working at some point in the future,but that's better than ,losing one's privacy to uncle Sam isn't it?
