I haven't had any problems, and I've had it disabled since July of 2009 when I began using the official Release Candidate of Windows 7.

I really don't do anything with my computer that puts it at risk because I know what to avoid. I don't even have any anti-virus or anti-malware software installed. Yes, I have no security software installed and I even have Windows firewall disabled.
You wouldn't ever know if you have any problems since :

1. You don't have security software installed,
2. You don't run a software firewall, and
3. You run with UAC off which allows malicious code to run at an elevated privileged.

This forum would never condone or recommend such a setup. Anyone else that reads this should realise that such a setup is an exceptional high risk one.
