Ensure 'Prevent device metadata retrieval from the Internet' is set to 'Enabled'

AltaNivel 1Automatizadawindows

Descripción

This policy setting allows you to prevent Windows from retrieving device metadata from the Internet. The recommended state for this setting is: Enabled. Note: This will not prevent the installation of basic hardware drivers, but does prevent associated third-party utility software from automatically being installed under the context of the SYSTEM account.
