Aker, once again thanks for the arrow pointing. So far so good. As you might have gathered, I'm pretty much learning as I go, so I appreciate your patience answering the noob questions.
In case there were any drivers as part of windows update, I just pulled my data drives out of the server (a HP ex49x) and clean installed the WHS2008 on a spare hard drive instead of setting up a virtual machine. WUMT initially downloaded 167 updates with a few of those specific to WHS. The main one was WHS Power Pack 3. The install disk I am using (HP Server Recovery Disk V3.0 HP ex49x Series 9/2009) appears to have PP2 on it already per a first run of the WUMT update history.
I still have to download & install the found updates with WUMT and run the update/install process a few more time to pickup any remaining updates. As I go I'm copying the updates out of the software distribution/downloads folder for off line storage. Each update folder contains an .exe file with other data.
The KB#'s you found appear to be updates specific to PP3. Since I haven't installed PP3 yet, I can't tell you if WUMT will actually find them when I run a search for downloads again.
From my first post, the writing is on the wall as to when MS will fully discontinue with the WHS updates. What I'm trying to do is have the updates available off line for any potential clean re-installs or recoveries of the OS (once these updates are no longer pushed). What is downloading are folders with .exe files and other data in them as well as what appear to be stand alone .psf files.
So my question here is, Can I use WSUS off line to install the updates I've downloaded or to compile a slipstream disk containing them (I'd prefer the former)? Or, once MS stops the update push (probably in the near future), am I updating the OS by placing the saved updates back into that software distribution/programs folder and then opening each of them one by one to run the .exe file?
