Vista's (and now Windows 7's) stupid Pictures and Videos folder type is NEVER useful for me. Whenever I see it I am ALWAYS disappointed and frustrated. It removes Explorer's basic functionality just because my folder has a picture in it. Here's how to disable automatic folder type discovery.

Luckily if you like the Pictures and Videos folder type and want to use it for specific folders, then you can turn it back on, on a case by case basis. The issue here isn't that there is such a thing as a Pictures and Videos folder type; rather it is the badly implemented automatic discovery feature.
