Someone please create a windows 7 like user interface or even XP like interface too and you got yourself a serious fan I might seriously recommend it to newbies and like there is just this love I have for windows 7 even though I really didn't use it for much but its so much more elegant in its own way than windows 10 like it can be a really fun experiment and I would be interested to see how that would pan out.
It would fail, and just be another corpse in the desktop OS graveyard.

Unless you ship your own hardware or get a vendor to ship your OS (see the above), and set up so the user can actually use it, you have to get users to install it on Windows hardware. So now your company is debugging broken consumer hardware without the help of the OEM. So that hopefully someone will install it on exactly that configuration for free.
This is not a winning business model.
