How to get explorer folders as default folder view?

Question

I like the style of of folder tree browser where there is an explorer pane on the left. In XP you can get this in View -> Explorer Bar -> folders. However, there doesn't seem to be a way to set this as the default view, at least through the Tools -> Folder Options menu. Do you know how to do this?

Also, is there a way to get this in Vista?

Thanks!
