First Ten Programs on New Install?

reddigitaldragon asks: "Some people re-install once a year, but if you're anything like me your machine is formatted at least once a month. After the OS is in, then come the favorite/must have/most used programs to install. My first installations for Windows (I use it; get over it): Trillian, Winrar, Firefox, Winamp, SmartFTP, Azureus, NMap, GKrellM, PowerDVD. What are your First 10 installed programs?"
