Improvements and fixes KB4493510 (17763.404)

Fixed an issue where applications that provide advanced options for integrated or external audio output devices stopped working on computers with multiple audio devices. This problem occurred with users who chose a sound output device other than the “default audio device”. Examples of applications that may stop working: Windows Media Player, Realtek HD Audio Manager, Sound Blaster Control Panel.
The update includes fixes for Game Mode. This feature will no longer affect the user experience when using popular software solutions for screen recording and streaming pictures.
Activation of Windows 10 Enterprise insider assemblies in Microsoft Azure virtual machines is allowed. Microsoft Azure is the only tested and supported host platform for Windows 10 Enterprise virtual machines.

Fixed an issue where the DeleteObject () object of a graphics device interface (GDI) caused the calling process to stop working when the following conditions were met:
The calling process was a WOW64 process and processed memory addresses over 2 gigabytes.
DeleteObject () was called in a device context that is compatible with the print device context.
Fixed an issue that prevented applications and callers from connecting to endpoints when using network interfaces that do not have a default gateway. This issue affected the following:
Failed to access the Internet on devices with DSL modems and PPPoE dial-up connections (usually used with DSL modems).

Web browsers and Win32 applications connected to the network were not affected by this problem.

Added a new group policy setting called “Allow Windows soft disconnect from network”. This setting determines how to automatically disconnect the PC from the network when Windows detects that the computer should no longer be connected to the network. Available along the path: Computer Configuration> Administrative Templates> Network> Windows Connection Manager.
When you turn on Windows, it will programmatically control how the computer is disconnected from the network (the disconnection will not be sudden).
When the option is disabled, Windows will immediately disconnect the computer from the network.
If not configured, soft software trip control will be enabled by default.
