How to Know If You Have a 32bit or 64bit Processor or Operating System

We usually encounter many programs/applications that require a 32 bit or 64 bit processor or operating system. And usually we ask ourselves “ Do I have a 32 bit or a 64 bit processor or operating system on my computer ?”. In this tutorial i will show you how you can easily find out weather your computer is running on 32 bit or 64 processor or operating system.

The difference between the 2 processors is the speed. Obviously, a 64 bit processor can process much more data quicker compare to a 32 bit processor.

When it comes to operating system, a 64 bit OS can only be used on a 64-bit processor. On the other hand the 32-bit OS can be used for both 32-bit and 64-bit processors.

So, how do you know if you have a 32-bit / 64-bit processor or OS ? Here’s how

  1. Click the Start Menu
  2. Click “All Programs”
  3. Click “Accessories then System Tools”
  4. Click on System Information

Now Look on the OS name and Processor at the right side. If you see “x86” then you have a 32-bit processor and if it is ia64 or AMD64 then you have a 64-bit processor. Obviously, you have a 64-bit operating system / processor if you have Microsoft Windows XP Professional x64 Edition installed on your system.
