The remote Windows host is missing a security update. It is, therefore, affected by an elevation of privilege vulnerability due to improperly allowing web content to load from the Windows lock screen.
A local attacker can exploit this, by connecting to a maliciously configured WiFi hotspot or by inserting a mobile broadband adapter, to elevate privileges and execute arbitrary code.
