httpd said:But if you have more then 31 days uptime on a windows system you have missed some important updates. But then again it depends on what and how you use the system if it matters or not. Almost the same goes for 10.3 but the updates are not as necessary in a security point of view for the normal user.
Windows updates, as frequent as they are, rarely require a full system reboot, especially for enterprise-grade software. Major service packs, yes, but I can't think of any critical update in recent history that required a reboot of my Windows 2003 server (needed because of Access). I would remember, because when you restart Windows 2003, you have to enter a reason for the reboot. You can't just restart the system on a whim. So the log would tell me what I was doing.
