64 bit systems are used for high end computer work and it is highly unlikely
that a home user would purchase one. The cheapest 64 bit Workstations cost
in excess of $3000 US and prices go up dramatically after that. However if
you really want to know just run this little app from Kelly T's site http://www.kellys-korner-xp.com/xp_tweaks.htm . Scroll way down to Line 258
and look across to the right side of the screen. She has an app that will
tell you if you have 32 bit or 64 bit.
