Issue using PXE to start a device from WDS
After installing KB4489868, 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. This may cause the connection to the WDS server to terminate prematurely while downloading the image. This issue does not affect clients or devices that are not using Variable Window Extension. 

Affected platforms:
  • Client: Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10, version 1803; Windows 10, version 1607; Windows 10 Enterprise LTSC 2016; Windows 8.1
  • Server: Windows Server, version 1809; Windows Server 2019; Windows Server, version 1803; Windows Server 2016; Windows Server 2012 R2; Windows Server 2012
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. 
 
Next steps: Microsoft is working on a resolution and will provide an update in an upcoming release.
