Question: Am I Running a 32-bit or 64-bit Version of Windows?

Not sure if your installed version of Windows is 32-bit or 64-bit? If you're running Windows XP, chances are it's 32-bit. However, if you're running Windows 8, Windows 7, or Windows Vista, the chance that you're running a 64-bit version goes up considerably.

Of course this isn't something you want to take a guess at.

Knowing if your copy of Windows is 32-bit or 64-bit becomes very important when installing device drivers for your hardware and choosing between certain kinds of software.

Answer: You can tell if you're running a 32-bit or 64-bit version of Windows by looking at information about your operating system installation in Control Panel.

The specific steps involved in determining if you're running a 32-bit or 64-bit version of Windows depends a lot on which operating system you're using:

Note: There are no 64-bit versions of Windows 7 Starter, Windows Vista Starter, Windows XP Home, or Windows XP Media Center Edition.
