You can get pedantic and argue that a Linux distribution isn't a fair comparison - but as stated - Windows has fewer vulnerabilities - is entirely correct - at least versus say Redhat and SUSE. Ditto the rest of it as far as I can see. Do feel free to provide factual examples of any actual errors ?
Nice try, but I don't have to prove a negative, you have to prove your original assertions. A little tip: if you're trying to use the Secunia database for it, be honest and add up all the versions of Windows. And leave out all the bugs that are applications, not core OS. You'll find that your assertion is then about as robust as Windows security - shaky at best.
