For comparison, it's always fun to read about my Windows 8 experience.
Not to open a can of worms, but what exactly were the issues with it other than the UI?
I see no actual reasons for your hatred of the OS other than "I can't take the time to learn a new UI because it needs to be identical to the last iteration of windows"...
Windows 10 is what Windows 8 should have been from the start, but to say Win8 was garbage simply because Microsoft attempted to compartmentalize things into more logical places is quite silly. (I won't defend the start menu however, that was very poorly thought out)
If you want to have a familiar UI, use an OS with a familiar UI.
You wouldn't buy a bicycle and complain it doesn't have 4 wheels like the vehicles you are used to driving, would you? It's nonsense.
In terms of Windows 10 however, I love it but I do have to warn that the forced Windows update can range from mildly irritating to completely breaking your system with bad drivers or forced new builds (Which you cannot revert back from without reinstalling, by the way).
I've had to re-install Windows on my tablet probably about a dozen times since I've had it installed in July because of new builds, and in fact even right now my build is partially broken already, and I've simply been procrastinating re-installing it because it
usually works okay.
On my desktop, I have to completely disable Windows update because it installs bad drivers for my hardware, and there's no option to disable the forced automatic driver installation without disabling Windows update entirely. Very irritating. EDIT: It appears this may have been fixed.
