If you want to do one better make sure to run ccleaner after deleting any
registry key to nuke any registry keys that may have been relying on it. Run
ccleaner 2-3 times and you'll save yourself from a world of hurt.

Microsoft Windows Mail and Outlook Express NNTP Protocol Heap Overflow

V. WORKAROUND
Deleting the all sub-keys of the following registry keys will remove the
'news' and 'snews' protocol handlers:
HKEY_CLASSES_ROOT\news\shell
HKEY_CLASSES_ROOT\snews\shell
If you want to do a thorough job of such mitigation as a Q&D fix, you
may also need to nuke the
HKEY_CLASSES_ROOT\nntp\shell
entry.
I can't easily test the viability of exploiting this via an nntp:// URI
just now, but "nntp" is normally registered (at least with OE -- can
someone check for Windows Mail?) with exactly the same sub-keys and
values as the "news" and "snews" URI handlers...
