Apps may stop working after selecting an audio output device other than the default
After installing KB4482887 on machines that have multiple audio devices, applications that provide advanced options for internal or external audio output devices may stop working unexpectedly. This issue occurs for users that select an audio output device different from the \"Default Audio Device\". Examples of applications that may stop working include: 

  • Windows Media Player 
  • Realtek HD Audio Manager 
  • Sound Blaster Control Panel 

Affected platforms:
  • Client: Windows 10, version 1809; Windows 10 Enterprise LTSC 2019
  • Server: Windows Server, version 1809; Windows Server 2019

Workaround: As a temporary solution, select the \"Default Audio Device\" in the options provided by the application; please refer to the application's user manual for details. 
For example, to set the Default Audio Device in Windows Media Player: 

  1. Open Windows Media Player > Tools > Options > Devices.
  2. Select the device and choose Properties.
  3. On the next dialog, from the drop-down menu under Select the Audio Device, choose Default Audio Device from the list.
 
You can then send audio from the application to the audio device you want in the per-application audio settings found under Settings > System > Sound > App Volume and device preferences.

Global DNS outage affects Windows Update customers
Windows Update customers were affected by a network infrastructure event on January 29, 2019 (21:00 UTC), caused by an external DNS service provider's global outage. A software update to the external provider's DNS servers resulted in the distribution of corrupted DNS records that affected connectivity to the Windows Update service. The DNS records were restored by January 30, 2019 (00:10 UTC), and the majority of local Internet Service Providers (ISP) have refreshed their DNS servers and customer services have been restored. 
 
Affected platforms:
  • Client: Windows 10, version 1809; Windows 10 Enterprise LTSC 2019
  • Server: Windows Server, version 1809; Windows Server 2019

While this was not an issue with Microsoft's services, we take any service disruption for our customers seriously. We will work with partners to better understand this so we can provide higher quality service in the future even across diverse global network providers. 
 
If you are still unable to connect to Windows Update services due to this problem, please contact your local ISP or network administrator. You can also refer to our new KB4493784 for more information to determine if your network is affected, and to provide your local ISP or network administrator with additional information to assist you.

Issue using PXE to start a device from WDS
After installing KB4489882, there may be issues using the Preboot Execution Environment (PXE) to start a device from a Windows Deployment Services (WDS) server configured to use Variable Window Extension.

  • Server: Windows Server, version 1809; Windows Server 2019; Windows Server, version 1803; Windows Server 2016; Windows Server 2012 R2

Workaround: To mitigate the issue, disable the Variable Window Extension on WDS server using one of the following options:

Option 1:
Open an Administrator Command prompt and type the following:

Wdsutil /Set-TransportServer /EnableTftpVariableWindowExtension:No

Option 2:
Use the Windows Deployment Services UI to make the following adjustment:

1. Open Windows Deployment Services from Windows Administrative Tools.
2. Expand Servers and right-click a WDS server.
3. Open its properties and clear the Enable Variable Window Extension box on the TFTP tab.

Option 3:
Set the following registry value to 0:

HKLM\\System\\CurrentControlSet\\Services\\WDSServer\\Providers\\WDSTFTP\\EnableVariableWindowExtension

Restart the WDSServer service after disabling the Variable Window Extension.
