I've been using 10 for more than a year. I still prefer 7 or 8, mainly because of the (relative) lack of spyware. 10 is a great system "under the hood." It just does too much spying.
My advice to people who have to use 10 is to get the Professional upgrade (gives you a bit more control over updates and some other settings), disable all the spyware you can (starting with Cortana), and get OCD about backups, including full-system backups, especially before installing updates. I make an image every morning and a clone every afternoon, and install updates immediately after one or the other. Then if an update bricks the system, I can go backwards in minutes.
I also have the Macrium Reflect recovery accessible from the bootloader, so assuming the machine gets that far, I can restore without even breaking out a screwdriver. And in case the machine can't get that far, I have it burned to a bootable USB stick, as well. And if that doesn't work, I have the bootable clone. And if that doesn't work, I have all my important files saved to an ioSafe and also online at BackBlaze.
As I've said many times, I never heard anyone who just had a data disaster complaining about having too many good backups to choose from. You can never have too many backups.
