Microsoft Defender App Guard issue

This article is bit different from most others. In this post I’ll be sharing a current issues I have with Defender Application Guard. If you have some suggestions of any additional troubleshooting, I’d love to hear, because currently, I’m not having much luck finding a solution.

The issue is that if I go into the new Edge browser and select a New Application Guard Window, I end up with:

image

WDAG Report – Container: Error: 0x80070013, Ext error: 0x00000001; RDP: Error: 0x00000000, Ext error: 0x00000000 Location: 0x00000000

I have tried the wdagtool command line tool with the following result:

I have also run a:

sfc /scannow

across my machine with no integrity issues.

If I dig into Event viewer | Application and services log | Microsoft  | Windows | WDAG-Manager, I see:

image

A Failure has occurred: HResult = The media is write protected., File = windows\hvsi\hvsimgr\container\hvsicontainer.cpp, LineNumber = 769, Function = NULL, Message = NULL, CallingContext = NULL, Module = hvsimgr.exe, Code = NULL

and in Event viewer | Application and services log | Microsoft  | Windows | WDAG-Service, I see:

image

Container service failed to start the container: The media is write protected.

I have the App Guard Service enabled in my Windows Features  as well.

I have tried:

  • Re-installing Windows
  • Re-running Windows install again
  • Removing all App Guard components, rebooting, reinstalling all the components again and rebooting
  • Installing Hyper V service
  • Installing Sandboxing Service

I am still trying to resolve this issue, and have tried quite a few knowledgeable people who haven’t had much luck either. So, if you have any suggestion of what may help, please let me know.
