Running XP as a virtual machine in Vista

Q. I have a computer that runs Vista Ultimate. However, some programs won't run on Vista; they require Windows XP. I don't want a second computer. I also don't want a dual-boot setup. I've heard that I can install XP as a virtual machine in Vista. Is this true? How does one set up a virtual machine?

A. Vista is an improvement over Windows XP. There are nice new features for you to enjoy. And, security is enhanced in Vista.

However, Vista isn't perfect. Not all software will run in it. And many users have encountered problems using old hardware.

Creating a dual-boot setup is one option. But for many people, creating a virtual machine is much better. You won't have to reboot in order to change operating systems. You can even work in both at the same time.

Before you install a virtual machine, make sure your computer can support it. You must be running Vista Business, Vista Enterprise, Vista Ultimate, XP Professional, or XP Tablet PC. You'll need at least 2 gigabytes of hard drive space.

You also need to consider RAM. You need 256 megabytes minimum for Windows XP. If you plan to run intensive programs in XP, increase that to a gigabyte.
