Well, I checked the options you said to check, all was well. I disabled it and then re-enabled it, then cleared the log. I'll see what happens on the next reboot. As far as the boot logging utility, looks interesting. I will play around with it as well, but I still want to know why the "Boot Performance Monitoring" stopped in the first place. Gotta love vista.... I'll let ya know if disabling/enabling and clearing got it working again.
