(lastly in a corporate environment systems are locked down, apps are
supposed to only come in versions the heldesk know to deal with, which has
not stopped ISVs from multiplying the web updaters that run sneakily in

find the user agent of such a beast it ends in the blacklist directly –
much less trouble than trying to follow which update web site they use
this week)
