Got this error too after updating to the latest windows 10. My VBox didn't run anything after I updated and installed Windows Sandbox. Tried to use vmware on friend's pc and got the error, and then i directed to the resolution in microsoft site (sorry i can't post a link, new account).
From there, try to disable the policy settings in gpedit.msc: Computer Configuration -> Administrative Templates -> System -> Device Guard -> Turn On Virtualization Based Security to
Disable.
And delete all registers in
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\DeviceGuard\
Then I downloaded the "
Windows Defender Device Guard and Windows Defender Credential Guard hardware readiness tool" (Google it, first link
, sorry can't post links, link's end is details.aspx?id=53337), extract and run the ps1 file in powershell as admin using
Code: Select all
& DG_Readiness_Tool_v3.6.ps1 -Disable -AutoReboot
After run the script, your computer will restart and will prompt you to disable credential guard on boot and one other prompt (i forgot), press F3 to accept and pc will boot normally.
Cheers.
