To exploit this flaw (in explorer), simply place a malformed (invalid
"size" field) .emf file in any directory, open explorer to that path,
and view as Thumbnails. Bang. In it's simplest form it's a DOS - it
affects all explorer windows, including File Open dialogs for many
programs.

The february 04 issue of MaximumPC lists the following registry key 
to tweak to help speed up your system. Seems to me this might have 
other benefits besides speed. :-)

Remove Image Preview by deleting this key:
 
HKEY_Classes_Root\SystemFileAssociations\Image\ShellEx\ContextMenuHandlers\ShellImagePreview
