Easy ways to check if your PC's CPU architecture is 32-bit or 64-bit

This wikiHow teaches you how to determine your Windows computer's bit count, which typically will be either 32- or 64-bit.

Things You Should Know

  • On Windows 7, right-click the Computer icon on your desktop and choose "Properties."
  • You can run 32-bit programs on 64-bit PCs, but not the other way around.

    Yes, open up the PC. Look for a big fan. Unscrew the fan. Underneath the fan is a processor. Take out the processor. Put in a 64 bit processor (must purchase separately). Apply thermal paste. Put the fan back on. Close the computer.

    Community Answer
    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.
