How do I tell which Operating System my PC has? Is my version of Windows 64- or 32-bit?

This is fairly simple to determine. First are instructions for Windows XP, then for Windows Vista and 7.

For Windows XP systems:

1. Click ‘Start’ in the lower-left side of your screen

2. Right-click on ‘My Computer’ (if My Computer is not under Start, look for it on your desktop)

3. Click on ‘Properties’

You will now be in the System Properties window (click to enlarge picture), which tells you everything you need to know about your operating system.

You can tell the operating system version at the top of this window. In the above example, both machines are Windows XP Professional. On the left is an example of a 64-bit XP system, and the right is a 32-bit version. As you can see, the 64-bit systems will identify themselves as 64-bit (“x64″) and the 32-bit systems won’t mention it at all.

Below the operating system info you can tell the version (on the left is Version 2003, on the right is Version 2002) and Service Pack information. On the left is Service Pack 2 and on the right is Service Pack 3.

For Windows Vista or Windows 7 systems:

1. Click ‘Start’ (also known as the Windows button, located in the lower-left side of your screen)

2. Right-click on ‘Computer’ (if Computer is not under Start, look for it on your desktop)

3. Click on ‘Properties’

You will now be in the System Information window, pictured below. This screen tells you all that you need to know about your operating system (OS).

At the top of this window you can see your operating system version. The version on this PC is Windows Vista Home Premium. If you have another version of Vista or Windows 7, e.g., Home Basic or Enterprise , it will display that version here instead.

Vista and Windows 7 will clearly identify whether they are 64- or 32-bit systems; the above is a 32-bit version of Windows Vista Home Premium.

That’s it! We hope that you have found this post informative. Feel free to send us a question of your own here!
