We've all seen these questions: "Why should I update my OS?" "Why should I use a supported OS? What happens when support is dropped?" I came up with general security reasons rather quickly- vulnerabilities and errors are discovered in an operating system, and patches are created to fix them. As I thought about it I realized that beyond this, I'm not really certain exactly what updates will do and won't do for an operating system. Can anyone point me to some resources to explain the details? Or can you speak to specific, non-security-related hardware & software errors that updates would fix? Of course some updates cause some incompatibility issues. Do you just remove the offending updates or do you stop updating totally? The counter-point: Wilders is populated by a few folks that run unsupported operating systems. I believe those folks use third party sources (or compile their own) to continue unofficial support for themselves. But I don't think anyone here just runs officially unsupported Windows 2000 without doing something to it. My goal is to more fully understand how updates affect security, performance, and the life of any operating system.
