How do I “Try Searching for All Photos and Videos”?

Windows Live PG comes back with that suggestion when there is nothing in a folder in PG, but doesn't tell you HOW to "search for all photos and videos".   In fact, I see no "search" function or button for photos and videos - only a "text search" function.

Nice of Windows to suggest you do something, but then not provide you the means to do it, or explain HOW to do it.    If this is a function you do in, say, "Windows Explorer" then it should say so - but it doesn't provide any detail other than to say, " "Try Searching for All Photos and Videos".

This is why people hate Microsoft.
