If your version of Windows is 64-bit, you're able to install both 32-bit and 64-bit software programs, so there are two different "Program Files" folders on your computer.

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.
