Query: Microsoft Shoots Self in Both Feet

It should be zero stars. Immediately on the Live OneCare download, Microsoft shot itself in both feet: Internet Explorer refused to download Windows Updates and Outlook Express denied the usual Font Changes. Over a week, and in the middle of a fruitless exchange with five supplier techies, I unloaded One Care and loaded Kespersky Anti-Virus 6. Then I found out that the only product Microsoft supports for free is Windows Update. There may be a message there! Finally, a Microsoft Techie, whose name I shall treasure forever, gave explicit instructions for open-heart surgery on the PC's Registry. After a week of frustration, my PC is faster than ever - with the very-protective Kespersky.
