You're right, but for reasons that people may not realize right away.

It isn't the content of the update you should be weary of (make this decision for yourself if you care this much) but it is the act of updating machines that will cause problems.

When a Windows machine updates (yes, even as of today - I had this issue just last week) it is in an indeterminable state until a reboot, even if the update doesn't require a reboot.

Are you rebooting all your windows servers for each little update too then?

No. In a perfect world yes, you would update immediately. However, it isn't practical. Define what's a good time frame (week, month, daily) for your server, its role, and your manpower and stick to that schedule.

I can definitely say that it is better to wait to update when you can reboot than to update immediately. Of course, if there is a really bad vulnerability, update immediately. Let the user know it's an exception.
