How to determine if your computer is 32-Bit or 64-Bit

When downloading a software program, you may be asked whether it's for an operating system that's 32-bit or 64-bit. Most PCs currently are 32-bit machines; their processors can handle 32 bits of data at a time.

Following these steps on a Windows operating system, you can determine whether your computer is 32-bit or 64-bit.

Difficulty: Easy

Time Required: 5 minutes

Here's How:

1. Open the System Information

   Open the Start menu, and click on Programs -> Accessories -> System Tools -> System Information

2. Look in the System Summary

   The System Information tool will display detailed information about your Windows operating system. Once opened it will show the "System Summary" – it’s an overview of your computer and operating system.

3. Look for the System Type Item

   On the right hand side of the window you will see a list of items. Look for the item called "System Type".

   The value of this item will tell you whether your computer is 32-bit or 64-bit:

   • x86-based PC: It’s a 32-bit computer.
   • x64-based PC: It’s a 64-bit computer.
