Automatic XP update changed many personal settings .. solved by re

After installing the early February collection of automatic updates on
Windows XP Home, powering off the machine, and powering it back on again, I
found my Windows environment to be markedly different: modern (not classic)
start menu, many items misssing from start menu, many desktop icons missing,
others not in their usual places, Symantec Anti-Virus failed on launch, and
many more.

Fortunately, a Start - Turn off computer - Restart restored the machine to
its familiar configuration.
