Check if your computer can Run 64-bit version of Windows?

If you are planning to install 64-bit Windows, then you must first assure if your computer system has a 64-bit capable CPU (processor) or not. The benefit of 64-bit version over 32-bit version of Windows is that, 64 bit handles large amounts of random access memory (4 GB of RAM or more) and is more responsive when running several programs at the same time or switching between them frequently.

How to Find if PC can run 64-bit version of Windows:

In Windows 7 or Windows Vista, do the following:

1. Open Start menu > Control Panel (change ‘view by’ to Large icons), click “Performance Information and Tools”.

  • In Windows 7, click View and print detailed performance and system information.
  • In Windows Vista, click View and print details.

2. See ‘System’ in Performance Information and Tools. ‘System type’ shows type of OS currently running and 64-bit capable shows whether you system can run 64-bit version of Windows or not. (If your computer is already running a 64-bit version of Windows, you won’t see the 64-bit capable listing.)

In Windows XP:

Just download the small and free SIW (portable) and run it. Click ‘CPU Info’ under ‘Hardware’ in SIW and check the ‘Number of Bits’ supported by your CPU (processor).

SIW - Number of Bits in CPU

If it shows 64 bits then CPU supports 64-bit Windows version.
