Jim;
You have 32 bit Windows XP.
Right click My Computer, click Properties.
If you have a 64 bit computer, it will say 64 bit on that page.
Also use the automobile test.
Did your computer with Windows XP cost more or less than your
automobile?
If your computer cost less, you have 32 bit.
If your computer cost more, you have 64bit.
Windows XP 64 bit with the required 64bit Intel Itanium processor is
much more expensive than any home computer.
