Last month, I blogged about Technology Management strategies and how to link good IT management back to a predictable IT budget. This April brings not only its usual tax day, but, crucial for IT management and business continuity, the end of support for the Microsoft Windows XP operating system. Unless you’re in the minority, look around, you’ll see Windows XP desktops or laptops. So what’s the end of support for XP have to do with increased network management costs? It means you’re going to need to upgrade old computers or risk unplanned downtime due to an exploited unsupported operating system.
