On the back of the Windows XP box, please read the statement
"For installation and use on one computer"
(see License Agreement for license terms).
To access the License Agreement on your XP computer, go to:
Start > Run and type: WINVER , and hit enter.
Then click on "End-User License Agreement".
You can also open XP's "Help and Support" and type: EULA
and hit enter. Click on "Questions and answers about the EULA".
The End-User License Agreement states quite clearly:
"You may install, use, access, display and run one copy
of the Software on a single computer...."

Additional installations requires additional licenses (Product Keys)
for each installation on a different computer.
