I don't think either one of those can really be called distributed ▪

A distributed system is set up where you can have many copies of a program running different servers. Each one is independent, and instances can be brought up/down without bother any other existing ones. For more in depth (and probably a little more accurate) information check out this wikipedia article on Distributed Computing

▪ Going by some definitions your windows applications could be called distributed, but it sounds like that is just a client, and not really doing any of the work.
