Microsoft is inconsistent with this. At one point, based on my understanding, "programs" meant traditional Windows apps and "apps" meant those "Modern" Windows 8 apps that they tried to foist on us. Then, at some point, it seems "apps" came to mean any application. Of course, Microsoft hasn't had consistency for a long time. In some ways, I miss the Microsoft of the 80s and 90s. Sure, they were totally evil, but at least they made good UIs.
