The reason Windows (and Microsoft itself) is not 6' deep yet is a relatively small number of commercial creative software like DAWs, graphics suits and CAD modellers. Yes, there's a huge amount of legacy software in CAM, plant control and whatnot, but that can run alright on all those Windows XP and 7 machines like forever.
All major software vendors who think that Windows has too much inertial following and that its users will embrace whatever fascist surveillance machine their computers become under this abomination of OS, and refuse to port their products to Linux, will be in trouble soon.
Out of all DAW developers, only Bitwig got this trend right yet.
