As a follow-up to my own post - and as Aaron closed his PrivBar blog for further comments - I want to offer an alternative that does not require any add-on software. Simply enter %userprofile% as address. This will show you the root directory of the user profile e.g. C:\Documents and Settings\user and tell you the user account being used. %userprofile% will switch the window into 'file mode'. Use 'back' or enter an HTTP URL, if you need to get back into 'internet explorer' mode.
