Re: "The patches are sent out as and when necessary"
You got it wrong.
It's install MS updates > reboot > reboot > make cuppa > reboot > make 2nd cuppa > finished? > broken.
In contrast, I get a single window on Ubuntu telling me there's updates for X/Y/Z, tell it to install and forget about it immediately.
(The more I use Linux, the more I find I like it...)
