How to tell the difference between Windows 64 bit Operating System and 32 bit Operating System is quite easy and very important when installing programs.
- To find out if your computer is running 32-bit or 64-bit Windows, do the following:
- Open System by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking System.
- Under System, you can view the system type.
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.
