Well you can turn off updates on most OS's, but not anymore... now MS forced it, they want everyone on 10. what I don't like is that I've installed very specific drivers, like I do NOT use the HDMI driver from AMD, but every few days it pops up in Windows update and 'fails' to install. I use DVI-D only, I do not need a driver for audio over HDMI.
Also I literally disable realtek audio in the bios because I have a sound card, but MS pulls my motherboard model and insists that I need the driver, it also fails to install every few days. I am extremely opposed to this decision.
Moreso, if you disable Cortana, the Cortana PROCESS never dies. if you intend to 100% terminate it, you have to navigate to it's location in file explorer, change the name of the (zip?) file and then the process can't find it's files. This works, but since the regular windows search feature is tied to Cortana, you have no search all of a sudden. Cortana is burned into the OS permanently. God damnit.
But multiple desktops rock. Play a game on desktop 2 with it running in windowed borderless mode, and then you can ctrl+win+left/right to instantly leave the game to an already configured desktop. Can't beat that.
Tons of improvements, tons of screw ups.
