Ok, so now I'm staying with Vista and just reinstalling. As I was getting ready to go back to XP, it hit me that this install of Vista was done as an upgrade from my existing XP Media Center Edition.
It jumped out at me as I started looking through the programs for what I wanted to save. I stumbled upon all of the HP crap that they love to cram into the little corners of your hard drive for whatever diabolical reasons they have.
I believe that almost all of the problems that I was having in Vista are a direct result of things not upgrading properly when I ran the upgrade install months ago. Outlook was crapping out on me, Windows Search wasn't working right, some other software wouldn't run for unknown reasons, and all sorts of crap.
After discovering this, I decided to break out the Vista DVD and do a complete reinstall of Ultimate clean and see what happens before regressing back to the XP days. I really do love Vista and despite the extra steps to get some legacy apps working, it is otherwise a much more secure and stable platform than XP was.
Since the reinstall, everything that was not working before is now working beautifully and I couldn't be happier.
Sorry about the false alarm.
