Do I want the 32 bit version or the 64 bit version?

You most likely want the 32 bit version - it is far more common than the 64 bit version. To be certain, please follow the steps below.

Windows has a useful FAQ on this matter - below is an excerpt.



1. What is the difference between 32-bit and 64-bit versions of Windows?

The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 32-bit and 64-bit versions of Windows are designed for use in computers with 32-bit or 64-bit processors, respectively.


2. Can my computer run a 64-bit version of Windows?

To run a 64-bit version of Windows, your computer must have a 64-bit processor. To find your computer's processor speed, do the following:


1. Open System by clicking the Start button, clicking Control Panel, clicking Performance and Maintenance, and then clicking System. You might have a slightly different configuration - look under "Settings" for the Control Panel if you do not see that. If you do not see "Performance and Maintenance," just go straight to "System."

2. Under System, you can view the processor type and speed. It will mention if the processor is 64 bit - it might not mention if the processor is 32 bit.


3. Why wouldn't Windows mention if my processor was 32 bit?

Back when 32 bit processors were first in use, they were the only option. There was no need to distinguish between '32-bit' and '64-bit,' so many processors do not self-identify as a 32-bit processor.
