Select the checkbox as shown below for Windows Defender Application Guard.

Cortana’s settings have been integrated into Settings: Cortana is a core component of Windows and users look to the Settings app to find Cortana’s settings. We’ve heard your feedback about discoverability, and with this build, we’ve made the change to migrate all of Cortana’s settings into Settings. You can access them by clicking the settings gear in Cortana, going to Settings > Cortana, or just searching for the setting you’re interested in.
