I've heard that it is possible, but it will break several things. For
instance Windows' help system relies heavily on IE components. Also
there are several programs using configuration frontends that are
actually rendered by IE.

Why not allow all outbound traffic from the webserver to port 80/tcp,
and set the proxy on the webserver statically to 127.0.0.1:9 via local
policies, with the domains required for automatic updates as exceptions?
That way it shouldn't be much of a security risk, IMHO.
