Uh, well, I'm updated to 2004..............for now. Blue screened in the middle of one of the "reboot/install" cycles (crashdump showed an Nvidia error) and my Sonic Studio control software for the Realtek audio was busted until I ran a repair utility. Also had one hang/reboot (with no crashdump) and a solid just hang after when it came back up. The first one, actually the mouse just stopped responding, but keyboard was still active. Got up to unplug/replug the mouse and as I plugged it in I heard my fans ramp up and it was at the BIOS screen on bootup.
Seems to be behaving for now though. Also ran a Windows Update which picked up a couple updates. Gonna watch it cautiously in case I need to roll back in the next 10 days.
