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