They already did all that with their enterprise edition, but they don't market it much. https://en.wikipedia.org/wiki/Windows_10_editions#Comparison...
Even with the somewhat limited pro edition, our IT is able to give us months and months of uptime for certain critical computers (i'm in biotech). Heck we have a W10 pro machine that handles building security and it has over 2 years of uptime.
The problem is the disconnect between HN and the average user who is dumb as rocks when it comes to tech. The average user expects the OS to magically take over the sysadmin duties. They just want it to be as simple and seamless as their phone - not an entirely unreasonable expectation given that the phone is sharing a lot of tasks that were only done on dedicated machines.
