It always happens to us. You have your favorite media player, graphics editor, HTML editor or whatever, and you install the latest codec or optional tool. Then suddenly your world is thrown into chaos: MP3 files open with an audio editor, images are opened with a program that takes 5 minutes to load, the sky turns red and Nazis are riding on dinosaurs!
This happens to me at least once a week. Somehow my default file associations get screwed up by something, which becomes a major inconvenience. In Windows XP it was very easy to modify File Associations by clicking View and Folder Options. In Windows Vista there isn't even a menu, or even a File Types tab... the option doesn't even appear if you right-click on the file. How do I change my File Associations now?
