Security patches, eh? Might fix the 17 bugs people complained loudly enough about, but probably creates 23 more bugs in the process, and ignores 47,000 other bugs at the same time. I honestly don't even patch Windows any longer for security reasons. What's the point? It's like welding a rusty iron patch onto a cardboard box. It takes 1 gig of space? Why in God's name should a patch be that big? I don't even have enough room on my HD to install that patch then. But maybe it's because it's just a release candidate and they'll shrink it down to .9 gigs for the official release. MS built-in firewall? Yeah, I wouldn't touch that with a 10-foot pole.

I prefer incrimental updates, because it's easier to fix if you break something, and it's easier to remember what you just did. If you install 20 patches / bugfixes at once, and one breaks, it can be hard to know which one just caused the problem. Talking about Linux here though. In Windows if something breaks you're screwed, so who cares.
