The thing I hate about Windows is the amount of constant attention it demands for updates, fixes, and just sitting waiting while it boots or hangs.
I want to turn it on, have it start quickly, and then I get on with whatever I want to do. Then I want to turn it off and have it shut down quickly. I want all updates to happen quickly and automatically, with no need for any input from me.
After 32 years of development, Windows still cannot do this.
