Windows 11 - Disable VBS (Virtualization-based Security)
Check if it's enable or not:
First you need to open System Information. Under System Summary, check for a row that says "Virtualization-based security." If it says "Not Enabled," you don't need to do anything else.
The first is to open Settings, click on Privacy & Security on the left pane, and you'll be greeted by a list of security features, Windows permissions, and App permissions. Click on the top one that says "Windows Security," and then click on Device security from the list that appears after that. Then click on "Core isolation details," which should be colored. This leaves you with a toggle for "Memory Integrity," which you need to turn off and restart your PC for it to take effect.
It is done via the Registry Editor. You can open by searching for its name from the Taskbar or by hitting Windows + R and entering 'regedit' in the text box -- click OK.
On the window that appears, there's an address bar that you can use to navigate directly to "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\DeviceGuard." On the right pane you should see a DWORD value called "EnableVirtualizationBasedSecurity." Open that and set it to "0." Restart your PC for the change to take effect.
