Through all the sites I've checked looking for a solution, the only people who have said something worked were people who were on a corporate network or had group policies in place. I know nothing of group policies so I wouldn't know if one had been set by something else on my computer. I don't know what group policy would make sense to have files misidentified anyway. They still work. It's just the icons are screwed up. It's weird.
Along those lines there is group policy editor but it is only on Vista pro, ultimate, and enterprise so that wouldn't be applicable to your situation. I'm not sure what else I can do to help.
