Windows下慎用內核隔離

1. 開啓內核隔離後只能經過註冊表關閉

 

2. 開啓內核隔離後, 默認會啓動hybrid-v, 這個東西和虛擬機是衝突的, 這樣就用不了虛擬機了.

 

3. 解決方法:

關閉內核隔離後, 再關閉已經開啓的hybrid-v

基本參考下面, 可能要重複幾回纔能有效的關閉hybrid-v

 

Powering on a vm in VMware Workstation on Windows 10 host where Credential Guard/Device Guard is enabled fails with BSOD (2146361)

Symptoms

Powering on a virtual machine in VMware Workstation prior to version 12.5 on a Windows 10 host where Credential Guard or Device Guard is enabled fails with a blue diagnostic screen (BSOD).

From VMware Workstation 12.5, you see error similar to:

 

VMware Workstation and Device/Credential Guard are not compatible. VMware Workstation can be run after disabling Device/Credential Guard.

 

 

For more information, see Windows 10 host where Credential Guard or Device Guard is enabled fails when running Workstation (2146361)

Purpose

This article provides steps to disable Credential Guard or Device Guard for a Windows 10 Enterprise host.

Cause

This issue occurs because Device Guard or Credential Guard is incompatible with Workstation.

Resolution

To disable Device Guard or Credential Guard:

Disable the group policy setting that was used to enable Credential Guard.

On the host operating system, click Start > Run, type gpedit.msc, and click Ok. The Local group Policy Editor opens.

Go to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security.

Select Disabled.

 

Go to Control Panel > Uninstall a Program > Turn Windows features on or off to turn off Hyper-V.

Select Do not restart.

Delete the related EFI variables by launching a command prompt on the host machine using an Administrator account and run these commands:

 

mountvol X: /s

copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y

bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader

bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"

bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}

bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO,DISABLE-VBS

bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:

mountvol X: /d

 

Note: Ensure X is an unused drive, else change to another drive.

 

Restart the host.

Accept the prompt on the boot screen to disable Device Guard or Credential Guard.
