You have to install Windows XP on the computer. It cannot be "preinstalled" on the hard drive.
Windows XP Professional (or Home) Minimum System Requirements
Published: August 24, 2001
Here's What You Need to Use Windows XP Professional or Home
PC with 300 megahertz or higher processor clock speed recommended; 233 MHz minimum required (single or dual processor system);* Intel Pentium/Celeron family, or AMD K6/Athlon/Duron family, or compatible processor recommended
128 megabytes (MB) of RAM or higher recommended (64 MB minimum supported; may limit performance and some features)
1.5 gigabytes (GB) of available hard disk space*
Super VGA (800 x 600) or higher-resolution video adapter and monitor
CD-ROM or DVD drive
Keyboard and Microsoft Mouse or compatible pointing device
Now, those are the absolute minimum requirements. In reality you need much more capability like a larger processor, more RAM, etc, for it to function acceptably.

Some programs seem to stop working after you install Windows XP Service Pack 2http://support.microsoft.com/kb/842242/
If you are going to install XP, get XP Pro rather than XP home. Microsoft will support it with extended support five years longer than XP home which is scheduled to have support discontinued when Vista debuts (which is this December). It also has far more security features and many other features not included or available with XP Home. and it is not that much more money.
