How to Tell If My Computer Is 32 or 64 Bit?

By Misty S. Bledsoe

A 32-bit computer and 64-bit computer process information differently. A 32-bit computer processes information less efficiently than a 64-bit computer. It’s important to know which type your computer is simply because device drivers that run on a 64-bit system will not work at all on a 32-bit system and device drivers built for a 32-bit system will not run on a 64-bit system. Finding out what your computer is only a matter of completing a few steps.

Step 1

Click on the “Start” button in the lower left-hand corner of the screen.

Step 2

Click on “Control Panel.”

Step 3

Click on “System and Maintenance.” Locate the menu on the left side of the box that popped up.

Step 4

Click on “System.” A new window will pop up. Scroll down to “System Type” and it will display “32-bit” or “64-bit.”

Tips & Warnings

  • If you aren’t sure if a program or device driver is compatible with 64-bit, you can visit Microsoft’s compatibility site at the link found in Resources.
  • Do not confuse drivers and programs. Programs that were built for a 32-bit system will run just fine on a 64-bit system. The only exception to this is some antivirus programs.
