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 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system. How can I tell if my computer is running a 32-bit or a 64-bit version of Windows?
To find out if your computer is running a 32-bit or 64-bit version of Windows in Windows 7 or Windows Vista, do the following:
1. Open System by clicking the Start button , right-clicking Computer, and then clicking Properties.
2. Under System, you can view the system type.
If your computer is running Windows XP, do the following:
1. Click Start.
2. Right-click My Computer, and then click Properties.
If you don't see "x64 Edition" listed, then you're running the 32-bit version of Windows XP.
If "x64 Edition" is listed under System, you're running the 64-bit version of Windows XP.
