What is best practice for installing windows updates on a single production web server. The server is fairly highly loaded with about 500k daily pageviews, and there's no test machine to pretest updates currently.
I've seen a lot of people recommend manually installing only critical updates..
What's your updating best practice?
Manually or Automatically?
Pre-test or not?
Some updates or all?
Any important workflow I should consider here?
Has anybody had any bad failures by not pre-testing updates?
(I think I know the answer to this one already)
