Not sure if your installed version of Windows is 32-bit or 64-bit? One quick way to tell is by looking at information about your operating system installation in Control Panel.

Identifying your system type is also important when upgrading. If you're running a 32-bit version of Windows, upgrading to 64-bit can help unlock the full potential of your computer.

While a 64-bit processor can run a 32-bit operating system, the reverse is not true. If your computer has a 32-bit processor, the decision has already been made for you.
