I applied 5 or 6 patches last night, and went to bed. This morning, the machine is in a reboot cycle. It never gets past the blue screen right before the desktop loads. That is, I get the DOS-like "Windows Loading" screen, then the Win2K splash screen with the loading indicator. When that goes away, the machine reboots. I've tried all three Safe Modes, Last Known Good Config, and Debug mode, and they all fail at the same point. Cross-posted at the MS help forum at that other site, too.
