In Windows Vista and 7

1. Click on Start.

2. Right-click on Computer and choose Properties.

In the System section you will see the System type row, which will display 32-bit Operating System or 64-bit Operating System, depending on which version you have installed.

In Windows XP

1. Click on Start.

2. Right-click on My Computer and choose Properties.

In the General tab, under System, you will see:

  • Windows XP Professional for a 32-bit OS
  • Windows XP Professional x64 Edition for a 64-bit OS

The main thing here is to be on the lookout for x64 Edition listed under System. If you don't see it, it means you're running a 32-bit operating system.

Why is it important to know what type of OS you have?

For several reasons actually, the most important ones being:

  1. Install the correct drivers for your system. Knowing whether you need to download drivers for x86 (32-bit) or x64 (64-bit) is crucial, because x86 drivers won't work in a x64 system and vice versa.
  2. Download the proper edition of software. Most software these days come with both 32-bit and 64-bit versions of their setup file and so, it's important to download the correct version. While 32-bit software do work on a 64-bit system, software designed for 64-bit won't work in a 32-bit OS.
