There's been a lot of talk about MS deliberately introducing new "features" via automatic updates that allow back-door access into anybody's PC, presumably because of some US law the requires the authorities to prevent "terrorism" etc.
You would think a company like MS could put together an operating system that didn't require critical updates every month or so.
With Vista it seems they are trying to cut out the 3rd party anti-virus/firewall products altogether - does anyone really want to trust MS completely with their PC's security???
