People list all the programs they've used. Microsoft Word, Microsoft Powerpoint, Firefox, Internet Explorer, [no, not a web programmer] Windows, Linux, Mac OSX, emacs, Visual Studio, gcc, g++, ssh, Putty, xterm, armed robbery, and emacs. (Typical start to an interview: "You listed emacs twice." "Really? Oops, sorry." "That's... not the reply I was fishing for, but 'oops' is acceptable.")
Frankly, I don't blame them. I looked through a stack of a dozen resumes on my boss's desk and noticed that every single resume listed Scrum. Somebody in HR is screening out candidates that don't list Scrum on their resume. I pointed it out to my boss and he just laughed and said he didn't think he could do anything about it. (I didn't look for other patterns, but I bet it's just as bad with particular software technologies.)
So listing every single piece of software you've ever noticed installed on your computer is a good policy unless you're personally handing your resume to the hiring manager. It makes a bad impression on technical folks, but that's better than getting your resume round-filed before anybody technical sees it.
(Note to self: next time job hunting, prepare different HR-friendly and techie-friendly versions of each resume.)
