Ugh. I've been using Vista for about a week now and it's slowly annoying the heck out of me. My cool "regsvr32 /u zipfldr.dll" doesn't work anymore. But thankfully, this post did the trick:

Simply, remove the following CSLIDs:
HKEY_CLASSES_ROOT\CLSID\{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31}
HKEY_CLASSES_ROOT\CLSID\{0CD7A5C0-9F37-11CE-AE65-08002B2E1262}
There's just so much bloat in Vista. :-(
Now, I need to find away to get Vista to quit trying to "recognize" MP3 folders and screwing up the customizing the view with "Album", "Artist", "Song" columns. *sigh*.
