I'm trying to run VirtualBox on Windows 11 and attempted to disable Hyper-V with `bcdedit /set hypervisorlaunchtype off`. However, System Information still shows: "A hypervisor has been detected. Features required for Hyper-V will not be displayed." Why is a hypervisor still active, and what else should I check?

Windows 11 can use the Hyper-V hypervisor for built-in security features, even when the main Hyper-V feature is disabled. Check Windows Features for related components such as Windows Hypervisor Platform, Virtual Machine Platform, and Windows Sandbox. Security options such as Core Isolation or Memory Integrity can also keep virtualization-based security enabled. Also, VirtualBox has its own virtualization support and doesn’t necessarily require Hyper-V.
I already checked the Windows Features dialog, but Hyper-V itself isn’t listed. The other closely related options appear to be disabled too. Is there another setting that could still be starting the hypervisor?
