How Do I Know If I Have a 32-Bit or 64-Bit Processor?

A 64-bit processor is able to operate faster than a 32-bit type. Certain operating systems use 64-bit versions to take advantage of such capabilities. A 64-bit processor can run a 32-bit operating system, and some 32-bit computers are capable of using 64-bit systems. Computers list such processor information. The location of the processor specifications differs slightly between operating systems. Check your system to find out how many bits the processor uses, and if it's able to run a 64-bit system.

Instructions:

1. Check processor architecture using Windows XP. Click the "Start" button. Right-click the "My Computer" icon. Click the "Properties" selection. Look at the figure beside "Processor," under the "Computer" heading. Then check under the system heading. Use a 64-bit system on the computer if "x64 Edition" is listed.

2. Check processor architecture with Windows Vista. Click the "Start" button, and click the "Control Panel" selection. Type the phrase "performance information and tools" into the "Search" box, and then click that listing. Click "View and Print Details" to see the processor information and operating system type currently in use. Use a 64-bit system if a 32-bit system is installed and the tag line shows the computer is 64-bit compatible.

3. Check processor architecture on a Windows 7 system. Click the "Start" button, then click the "Control Panel" option. Type "performance information and tools" in the "Search" box, and click the "performance information and tools" listing. Click "View and Print Detailed Performance and System Information" to see the processor specifications and current system type. Look for the tag line stating "64-bit compatible" before attempting to install a 64-bit system.
