This policy setting determines whether the Windows device is allowed to participate in cross-device experiences (continue experiences).
If you enable this policy setting, the Windows device is discoverable by other Windows devices that belong to the same user, and can participate in cross-device experiences.
If you disable this policy setting, the Windows device is not discoverable by other devices, and cannot participate in cross-device experiences.
If you do not configure this policy setting, the default behavior depends on the Windows edition. Changes to this policy take effect on reboot.
