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

How do you check your computer bits?

In your Windows 10 or 8 Settings, head to "System" and then "About."
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.

Question

Is there an easy way to install a 64-bit processor?

Community Answer

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.

Question

What is a 64 bit PC?

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.

Running a 32-bit program on a 64-bit computer is completely fine, and is often necessary when using older programs on your PC.
