Why are you having so many problems? i have been running windows 10 now for nearly 2 weeks, yes it is a record for me, it normally lasts two days.
No problem with browsers, I use cent browse, is this high contrast dark mode a hidden feature?
As for the next major version, I heard it will be in May that it is released.
I expect I will be back with windows 8.1 by then unless i have updated the computer, then I will have to see if windows 8.1 works with the new Ryzen
