Zelandeth, on my 'puters I have them do automatic checks to see if there is anything they think they need, but all they are allowed to do is to let me know. None of them are authorized to willy-nilly go out and download and install ANYTHING - even if it's from my computer manufacturer.
When they let me know they want something, I do a check in several places to see what experience has been with that update (usually over at least a week) before I let any of my machines download it. This comes from having jobs that depended on 'computers as tools' for over a quarter century.
I've seen what jumping on an update too early can do to a business.
When I was working in the Bell System one or our high-level managers had our computer folks cut us over to a new release on a weekend. When we showed up Monday, the primary application for all 219 workstations our engineering department used wouldn't run.
The recovery took us nearly a week. That's a week with over two hundred engineers not accomplishing anything. The people depending on us were NOT amused.
Later, when I had my own business, the 6 computers and one server were controlled very tightly because the company would likely not have survived if they all went down. There were nightly backups, of course, but even with that, trying to recover from a computer disaster (and the loss of productivity) could have been very damaging.
BTW, I just moved one of my personal 'puters to a new OS release (OS X 10.3.1) now that it has proved to be compatible with my primary applications, etc. The two others, though, are still running 10.2.6 and 9.2.1.
I run a happy LAN. /ubbthreads/images/graemlins/grin.gif
