How do i determine if i'm running 64-bit Windows?

Hi folks,

Is there a way to determine if my Windows (Home XP SP2) is a 64-bit version? I attempted to download a new modem driver and was offered 2 selections: a 32-bit XP version, or a 64-bit XP version.

on the bootscreen where it says windows xp, then has the loading bar along the bottom, itll say windows xp 64 bit edition

Ooops, I've just figured it out. My "Windows XP Home SP2" is 32-bit version.

What I did was:
(1) I first went to the DOS command prompt;
(2) I then typed "edit";

The DOS editor show up. In a true 64-bit environment, "edit" is disable.
