I try to install windows sandbox in my windows 10 home

Windows Sandbox cannot be enabled on Windows 10 Home. The workaround you most likely used, does not even work, and has never actually worked. However, when you attempted to enable Windows Sandbox, it also enabled Credential Guard and Device Guard.

The first thing you need to backup any critical files you cannot live without. Depending on the state of your system you might decide it's time to simply reinstall Windows 10 Home. An alternative is to upgrade to Windows 10 Professional so you can Enable Windows Sandbox then disable it properly. The following suggestion was written against an assumption that Windows Sandbox was properly enabled and not left in a broken state due to a workaround solution on Windows 10 Home.

1. Windows Security -->> Device Security -->> Core Isolation -->> Memory Integrity -->> Select Off

2. Since you are using Windows 10 Home you will have to install the group policy editor to perform next step.

3. Set Local Computer Policy ->> Computer Configuration ->> Administrative Templates ->> System - Device Guard ->> Turn on Virtualization to Disabled

4. Be sure Enabled with UEFI lock is not enabled.

5. Download the Device Guard and Credential Guard Hardware Readiness Tool and run the following command as an Administrator.

   • DG_Readiness_Tool_v3.6.ps1 -Disable -AutoReboot

6. You also need to disable both Hyper-V and Windows Sandbox. The following commands assume you are running Windows 10 Professional or Windows 10 Enterprise.

   • Dism /online /Enable-Feature /FeatureName:”Containers-DisposableClientVM” -All

   • Dism /online /Disable-Feature /FeatureName:”Containers-DisposableClientVM”

   • Dism /Online /Disable-Feature:Microsoft-Hyper-V

7. You should reboot your machine at this point

• Windows Sandbox Feature enables windows defender credential guard feature sets. Does not play well with VMware Workstation

• Manage Windows Defender Credential Guard

• VMware Player and Device/Credential Guard are not compatible
