Can my computer run a 64-bit version of Windows?

To run a 64-bit version of Windows, your computer must have a 64-bit-capable processor. If you are unsure whether your processor is 64-bit-capable, do the following:

1. Click to open Performance Information and Tools.
2. Click View and print detailed performance and system information.
3. In the System section, you can see what type of operating system you're currently running under System type, and whether or not you can run a 64-bit version of Windows under 64-bit capable. (If your computer is already running a 64-bit version of Windows, you won't see the 64-bit capable listing.)
