Hmm.. who really does that? Oh wait..

Windows updates cost nothing though.

They also don't scare you into updating, they just force the update down your throat.

@RealKC "UPGRADE TO WINDOWS 10 NOW, it's free only for a limited time! We already downloaded the upgrade for you so you only need to click this button!"

Sure, that's not trying to scare the user, but limited time offers are always a bit meh.

How does it know which programs do that?
