Most new computers come with Windows XP installed, so many people never have to install it. However, you may need to install Windows XP if:

•	You replaced your hard disk drive with a new hard disk drive that does not have Windows XP installed.
•	You are reinstalling Windows XP on a computer because you want to clean off your hard drive and remove any unwanted programs, such as spyware.
•	You purchased a computer without an operating system.

Fortunately, you do not need to be a computer expert to install Windows XP. Installing Windows XP is a straightforward process that takes between one to two hours. Of that time, you need to be present for only about 30 minutes.

•	Pre-installation checklist
•	Install Windows XP

Note:  If you have a computer with an older operating system, such as Windows 98, Windows ME, or Windows 2000, you should upgrade to Windows XP instead of performing a clean installation.
