I am not talking about Windows updates here. But even if I was, there are things wrong with it. One example, that frequently bites me on my gaming OS:
Windows 10 by itself decides: "Hey, I'm going to replace your installed graphics card driver with some other version, that I will find myself online!" Then next time I start this OS, I get crashing graphics card driver and need to go and look on AMD website for the correct drivers, installing them over whatever crap Windows installed. This has happened at least 3 times already and it is pissing me off. It would probably be better to deactivate automatic Windows updates completely and then try to have a manual selection of installed components. But even then I could not be sure, that it will not try to replace my installed drivers with crap.
