Follow this guide to find out if you're using 32-bit or 64-bit Windows, for any version.

    Find your processor type. Since you can have a 32-bit operating system installed on a 64-bit processor, it may be helpful to know if you’re actually running a 64-bit processor. With the System Information open from the previous step, click Device Manger in the left frame.
    • Select Processors from the list on the left. Click the “+” sign to expand the categories. Double-click on your processor. If you have multiple of the same processors listed, that means you are running a multi-core processor. Double-click on any of the listed options.
