You’ve taken the leap into Windows Vista, but once in awhile, your heart yearns for the classic features and functionality of XP. Maybe you’ve got software that doesn’t yet work in Vista, or maybe you just want to see how a web site looks in Internet Explorer 6. You could dual-boot XP and Vista, but switching between operating systems in that setup takes too much time.Instead, you can quickly toggle between Windows versions with an XP virtual machine running inside Vista using the free Virtual PC 2007. Here’s how.

What you’ll need

  1. A Windows XP setup disc with a license.
  2. The free Virtual PC 2007 download.
  3. About an hour, depending on how fast your computer is.
