Known Issues in KB4499167 Windows 10 1803 17134.765 Cumulative Update

Symptom 1

The post installation of this update may cause problems while 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 lead the connection to the WDS server to discontinue prematurely. It happens while you make an attempt to download the image. However, this issue will not affect devices or clients that are not using “Variable Window Extension”.

Workaround

First of all, you need to disable the Variable Window Extension on the WDS server to mitigate this specific problem. You can use one of the below-given options for that –

Option 1

Step-1: Open Run dialog box by hitting “Win + R” keyboard shortcut keys in one go. Type cmd and then jointly press Ctrl + Shift + Enter keys.

Step-2: Once UAC prompts up, hit Yes to proceed ahead.

Step-3: Upon the launch of an elevated Command Prompt, type the following –

Wdsutil /Set-TransportServer /EnableTftpVariableWindowExtension:No

Option 2
  • Get access to Windows Deployment Services.
  • Here, expand Servers and execute a right-click on WDS server. Choose Properties.
  • Switch to the TFTP tab and uncheck the option namely Enable Variable Window Extension.
Option 3
  • Here also, open Command Prompt with admin rights and go to the below-mentioned path.
HKLM\System\CurrentControlSet\Services\WDSServer\Providers\WDSTFTP\EnableVariableWindowExtension
  • Set the value to 0.
  • Once you successfully disable the Variable Window Extension, you need to reboot the WDSServer service.

Microsoft is working on a workaround and till that you can try out any of the above options.

Symptom 2

Certain operations will tend to fail that you execute in folders or files that are on a Cluster Shared Volume (CSV). For example, while you try to rename, you may receive an error STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5). Furthermore, this happens when you perform the operation on a CSV owner node from a process that does not have admin rights.

Workaround

You can try out one of the following –

  1. Do the operation from a process that holds admin privilege.
  2. Secondly, execute the operation from a node that does not have CSV ownership.

In the forthcoming release, you will receive an update from Microsoft as they are working on the solution.
