"previous System Shutdown Was Unexpected"

This dumb, uninformative, repetitive Event ID has been my most persistent, random, & most often logged Event Viewer error message since I clean installed Vista Ultimate 64-bit from a retail box the most part of a year ago. It has also been the primary cause for my biggest disappointment with Vista & strong evidence of Vista's failure as a reliable OS (not to say that this is the only evidence for such failure). My unrelenting search for relief has been just as persistent & has proven totally unsuccessful to date. However, my search has still been a learning experience. What have I learned? The following is not a complete list:

1. Windows users have been experiencing the same frustration (same issue) for several years going back to earlier Windows Op Systems.
2. This event has been reported by Windows users on a variety of platforms, PC brand models, and both Vista 64 & 32 bit versions.
3. No one cause has been identified as the trigger for this event - nor have I found that any effective remedy/work-around has ever been posted either on tech web sites, Microsoft newsgroups, or the Microsoft Knowledge Base................
