How to check
if VBS is enabled in Windows 10 or 11
In Windows 10 and 11, VBS is usually turned on by default. However,
admins can confirm if it is enabled by following this process:
Search for the System Information app in Windows search.
Open the app
Open the app.
Find the VBS status
Scroll down to the Virtualization-based security
row.
Check the result
If it says running, VBS is enabled.
How to disable VBS in
Windows 10 or 11
Open Core Isolation
Search for Core Isolation in Windows search or open
it from System Settings.
Turn off Memory Integrity
Turn off Memory Integrity (if it was on).
Restart the system
Restart the system.
Open the System Information app.
Check the VBS status
Scroll down to the Virtualization-based security
row.
Confirm it is disabled
If it says not enabled, VBS is disabled.
If VBS is still enabled
It must be disabled from the system registry (admin access plus
experience may be required) by following these steps:
Open Registry Editor
Open and run regedit to open the registry editor.
Navigate to the DeviceGuard
folder
Navigate to the folder:
Computer\\HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\DeviceGuard
Change the registry value
Open the file named EnableVirtualizationBasedSecurity
and set its value to 0.
Close Registry Editor
Close regedit.
Restart the PC
Restart the PC.
Confirm in the System Information app that VBS is disabled.
If VBS is still active
If after these steps you see VBS is still active, follow these steps.
For anyone still having trouble, what worked for me was:
Disable Memory Integrity
Disable memory integrity from core isolation.
Change
HypervisorEnforcedCodeIntegrity
In
HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\DeviceGuard\\Scenarios\\HypervisorEnforcedCodeIntegrity,
set value for 'Enabled' to 0.
Change WindowsHello
In
HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\DeviceGuard\\Scenarios\\WindowsHello,
set value for 'Enabled' to 0.
Restart
Restart.
Check System Information - VBS should not be running.
