MarkWatson asks: "I keep two Windows machines: a Windows 2000 laptop (bought with XP, but installed an old Windows 2000 license and Linux) and a desktop with XP (dual boot to Linux). I would like to avoid ever buying a PC with Vista, a situation that looks good because I believe both my Windows systems are reliable, fast, and will service my Windows needs for the long term. My problem is this: I like Windows 2000 better for a few reasons, but mainly because the license is transferable. I would like to still be using Windows 2000 5 years from now in a secure and reliable way (again, just for when I need Windows). Since I am far from a Windows expert, I would like to know your strategy for archiving Microsoft's latest Windows 2000 updates, and generally dealing with security issues. My strategy is to set my firewall up to run in stealth mode and not use Windows for general web browsing. Any suggestions will be appreciated!" How would you keep an old Windows OS (like Win98, and WinXP in another year or two) running long after official support for it has ended?
