Application Guard Closing Browser
Hi All, I am implementing WDAG in my organization. I am testing with the MS Edge browser. After configuring the "Network Isolation" settings, every time I browse to an "untrusted" website, my current/non-WDAG browser closes and the WDAG browser instance opens. Is there a setting that keeps the current/non-WDAG browser open when the WDAG browser instance opens? Thanks!

Defender Application Guard issues
I have a new Surface pro 7 running Windows 10 Enterprise, all patched and updated. The machine is Azure AD joined and managed by Intune on a M365E5 license. Every time I try and access ANY website in Edge WDAG launches and fails! So, I have two issues: 1. Why does Windows Defender Application Guard launch for every web site? 2. Why does it crash So the error from the browser after the crash is: WDAG Report - Container: Error: 0x80070013, Ext error: 0x00000001; RDP: Error: 0x00000000, Ext error: 0x00000000 Location: 0x00000000 If I look at Event viewer | Applications and Services | Microsoft | Windows | WDAG-Manager | Operational - I see: A Failure has occurred: HResult = Unspecified error, File = windows\hvsi\hvsimgr\manager\isolatedapplauncher.cpp, LineNumber = 376, Function = NULL, Message = NULL, CallingContext = NULL, Module = hvsimgr.exe, Code = NULL and 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 also C:\WINDOWS\system32>wdagtool.exe cleanup RESET_PERSISTENCE_LAYER Terminating HvsiMgr.exe HvsiMgr.exe process not found Performing cleanup and restarting the container * [WDAGTool] - Failed to reset the container. - HRESULT: 80070013 * [WDAGTool] - The hvsi cleanup tool has failed. - HRESULT: 80070013 A. I have tried enabling and disabling Hyper-V and WDAG on the device. They are all on now B. I have disabled and re-enabled WDAG using PowerShell C. I have run a system file scan with no errors Suggestions?? Thanks Robert

Windows Defender Security Center - Application Guard
So I turn on Application Guard, but when I expand Application Guard I am seeing Turn on managed mode for a large amount of PCs. How do I turn on this managed mode, so I can also improved my secure score.
