Long time windows user: you can disable windows update in the services menu. Open run --> services.msc
I know about this already, but the point is that end user experience for me had been getting worse than Windows7 for example (not talking about the UX here). The fact that i have to use powershell or service control center to control the stuff is just not nice. I think an end-user should not be forced to go to regedit to stop Microsoft to install crapware like candy-crush etc.
