~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I really object to this philosophy because it does not let a person
plan the downloading and installation of updates - some of which will
require a reboot.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Feel free to elaborate on how it prevents this.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
What do large corporate installations of Windows do here?
Do they run their own caches of the Windows updates?
Push out updates from servers rather than have clients pull?
Is it all done with SUS?
Is SUS usable on a single node, in place of WU?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There are a number of patching solutions for Windows, some push-based
and some pull-based.   Many folks use SUS in some capacity, even if
augmented by 3rd party solutions.

SUS requires AU, but the admin can control what patches are available
and when they are installed.

It's all explained in the SUS docs, and at http://www.susserver.org

Went to windows update last night w/ XP Pro.
Redirected to the v5 version.  I was asked to install
the new Windows Update software...downloaded the WU
software...copied the files...then saw
registering...kinda thinking that it was checking for
a valid registration or license.  No updates needed
according to WU.  XP SP2 is not available via WU for
XP Pro yet.

Now, I checked the Automatic Update service to see if
it was turned back start automatic as I always have it
disabled.  Yup, it was set to automatic and it was
started.  I stop and disable automatic update service,
and try WU.  Get error stating that the automatic
update service must be enable to use WU now.  Has
anybody else head of this?  Once again, we must have
services that we do not want enable.  I can not
believe that they are forcing user to turn on the
service to use WU.

I discovered this when testing out v5beta and had to do a checkpoint
recovery to restore version 4.  If you don't install the latest
Windows Update software (if, for example, you have all Active X stuff
set for prompting and you say "no") then you don't even get to 1st
base and Windows Updates (via a convienient mechanism) are not available.
IMHO, this sucks big time.

What I see Microsoft as doing is pretty much forcing everyone to turn
on Automatic Windows Update.  Why leave it as a control panel option,
I've no clue.  Same with BIT (Background Intelligent Transfers.)
For the millions of users out there that are likely subject to viruses,
etc, I'm sure it will help make things better, but for people who would
fit into the "power user" class, it's a real pain in the arse.

The help for the "Windows Update" web site suggests that it is
possible to get updates without Automatic Updates.  Is the help
out of date or is there a way to still do it without AU on ?

If you were a conspiracy theorist, you'd say this was Microsoft's way
of being able to do more automatic updates before announcing a security
vulnerability and mitigate the impact of 0-day exploits (developed through
reverse engineering of changes.)
