OK, gave it a try, but had some scary consequences. The KB
uninstaller hung at some point, loading the CPU at 100%, and
stayed there for 30 minutes. I tried to re-start the
uninstaller and even attempted to run the new update, but
they both recognized the hung process and refused to run. I
couldn't even kill "spuninst" in Task Manager. So, I killed
the power, aware that I risked frying the system. Luckily,
when I restarted, I was prompted to try a prior restore
point, which worked. Went to Windows Update (I update
manually), and it showed the update as available for
installation, which I interpreted to mean the uninstaller
actually did its work. I selected it and and it completed.
However, after all that, the problem still remains. Whew!
