Sorry, what? On Windows machines, due to the lack of package management, installing software is not a matter of "click, click, done." You have to google the program, navigate to the website's download area, find the right link, download it, execute it. It asks if you're sure it isn't a Trojan or something, which you promptly ignore (and learn to ignore every other "are you sure you want to execute foo.doc.exe?" popup).
Package management ('done right') is a matter of "click, click, done." Installing software on Windows is an absolutely terrible experience.
