The process of converting Windows evaluation to the standard version involves a few steps. First, you'll need to purchase a license key from Microsoft or an authorized reseller. Once you have the license key, you can enter it into the activation window in your existing evaluation copy and then select "Upgrade" instead of "Activate." This will start the upgrade process, which should complete within minutes depending on your internet connection speed. After that is done, you will be running the full version of Windows with all features enabled.
