You can turn off in atleast Pro (never tested them in Home, but if GPE is disabled in home, these changes be done in the registry But you are going to have to make a note of what changes you make.)
Auto Restart: GPE -> Computer Config -> Admin Templates -> Windows Components -> Windows Update -> "No Auto-restart with logged on users for scheduled auto updates...". You might want to look at the other options in there as there might be other things you might wish to turn on/off.
One Drive: GPE -> Computer Config -> Admin Templates -> Windows Components -> OneDrive -> prevent the use of OneDrive for file storage.
You can remove all of the Windows apps with a powershell script, and then you just have to shove a modified start menu layout in the default profile before capping the wim file to roll out your installs from.
If they would earn their money, and make actual useful innnovation, instead of being beat at their own UI game by third parties, like windows management, and keyboard macros etc etc, then 10 would be awesome. Hell even windows 10 task manager is crapper than the third party alternatives.
Sorry misread the comment. Never looked into any 3rd party software to do this.
> now what about 1/3 of screen so I can use this 55" 4k monitor properly
That sounds like a harsh thing to bash Windows 10 about but hey what ever floats your boat. If its 3 Windows of the same program Then you can use "show windows side by side" and while it might not "snap" how you want have a look at AquaSnap to help better manage your Windows. Single License is $13 but comes with a free trial to give it a try first. There is prob a OSS alt, but I've not looked.

Trying to keep that "one Windows for everybody" idea going is hurting them.
For large companies, I think Windows 10 could actually be really nice and efficient to use. It's faster and has some important new features (the new task manager is way better, especially for developers). It's just the retail version which includes a lot of garbage to compensate for the lower revenue.
