Thanks for the reply, but, that's exactly how I cleared the web pages from
the Taskbar's Address Toolbar AutoComplete History.
I searched the registry and the hard drive and that's when I realized only
some of the names matched my old searches. By examining each name, I have
determined they are mostly actual files and shortcuts on my Windows
Desktop, which is unexpected behaviour at best (I rate it as a bug).
There is nothing in the docs or the MSKB about this bug, so I don't see any
way to fix it, other than completely disabling AutoComplete, which defeats
the purpose of the whole exercise (clear the history completely, instead of
only partly).
Oh, well, that's so typical of my Windows experience, I won't bother
wasting any more time on the bug.
