Information

This policy setting allows you to control the network connectivity state in standby on modern standby-capable systems.

The recommended state for this setting is: Disabled.

Disabling this setting ensures that the computer will not be accessible to threat actors over a WLAN network while left unattended, plugged in and in a sleep state.

Solution

To establish the recommended configuration via GP, set the following UI path to Disabled :

Computer Configuration\Policies\Administrative Templates\System\Power Management\Sleep Settings\Allow network connectivity during connected-standby (plugged in)

Note: This Group Policy path may not exist by default. It is provided by the Group Policy template Power.admx/adml that is included with the Microsoft Windows 10 Release 1607 & Server 2016 Administrative Templates (or newer).

Impact:

Network connectivity in standby (while plugged in) is not guaranteed. This connectivity restriction currently only applies to WLAN networks only, but is subject to change (according to Microsoft).
