I agree Windows 10 has a lot of features and improvements that are nice to have. It is the reason I upgraded myself to Windows 10, however I don't do an "upgrade" like most people have I always do OS Installs on a fresh format usually on a new hardrive with the old one still there as a backup.
After using windows 10 for months now however I must confess it also has features that I extremely dislike so I have both gained and lost. Windows update on windows 10 is no longer optional it is a mandatory process with a mandatory reboot. This along with a few other "features" has caused me some headache. I've managed to mitigate most of them. Its much more manageable now though since I figured out how to break part of the automatic reboot process since part of it is controlled by the task scheduler but it required changing ownership of several files and making them read only.
