After spending nearly 3 days setting up my new laptop, which came with Windows Vista Business (and wasn't available with XP) Vista did an automatic update which disabled my gigabit NIC card. Nothing I could do would get it back (I couldn't get a system restore point before the updates -- too many restores in between pushed it out the end).
So, now at 9:50 pm, I've finished pulling off my critical data and I'm doing the only thing I can do -- restore the laptop to the factory Vista configuration, losing everything I've installed, set up, tweaked, etc. I expect to be up until 2 or 3 am re-installing those necessary programs that I'll need at work tomorrow.
Microsoft, ES&D for bringing this piece of garbage to market when, clearly, it's not ready for prime time (or anything close).

. . . continue on until I get to go to bed.
