With the capacity of memory more and more large, 32-bit system obviously can not meet our requirements, so now with more than 64-bit system of people more and more, many friends may be like you, in the update video card, do not know their own system is 32 or 64-bit? In fact, most of the XP are 32-bit, 64-bit XP usage is very small, so you should be 32-bit XP

To see if the system on your computer is running a 32-bit 64-bit version of XP, you can view it in a few simple steps:

1. Right-click My Computer on the desktop, and then click Properties

If you do not see the x64 version listed, you are running a 32-bit version of Windows XP.

If "x64 version" is listed under System, you are running a 64-bit version of Windows XP.
