Add to this that even if you manually monitor the offered updates before allowing installation, you don't know the nature of what you are getting. For example, if they say, 'Security Update', and 'fixes a vulnerability', what does that mean? It could be protection from hackers or it could be officially sanctioned malware. And those who say, 'If you've done nothing wrong you have nothing to fear,' don't know the real world. I have a licensed XP, but I still don't trust Microsoft.
