+
+- If you disable this setting, booting to Windows To Go when a USB device is connected will not be enabled unless a user configures the option manually in the BIOS or other boot order configuration.
+
+If you do not configure this setting, users who are members of the Administrators group can make changes using the Windows To Go Startup Options Control Panel item.
