I saw two clients today who had their XP Start Menus set to the "classic mode."
In classic mode your Start Menu looks the same as it used to in Windows 98-Me, but the new XP menu is much more functional and easy to use once you understand it.
The XP menu is divided into two sides. The right side lists all of the utility type of programs and features such as My Computer, My Network Places, My Documents, etc.
The left side changes. As you use programs often they appear and move up or down the left side accoding to how often you use these programs.
You can manipulate the settings of your Start Menu by right clicking on the Start button and choosing Properties. Click Customize to make even more changes.
