The other irritating thing with Windows is when you do need a reboot in the middle of the day and it declares that it's got 60 updates to install before it will reboot and takes three hours to do it.
Or you just get a 1000 clicks in the middle of nowhere, log on with a sattellite link. and your screwed. Or your near the very end of your monthly allowance and ..... Or Or Or. F@$$ windows.
