Is Hyper V really disabled?

Hyper-V must be disabled to use the Android Emulator Hypervisor Driver for AMD Processors. However, unchecking "Hyper-V" in Windows Features Dialog might not guarantee that Hyper-V is disabled. Quite a few features in Windows 10 will enable Hyper-V implicitly. Users may not even know Hyper-V is activated when they enable one of these features.

To our best knowledge, these includes Virtual Machine Platform, Windows Hypervisor Platform, Windows Sandbox, Core Isolation, Credential Guard. Additionally, Windows Subsystem for Linux version 2 requires Virtual Machine Platform, meaning that it implicitly requires Hyper-V. This list is not exhaustive, please notify us on our bug tracker if you find an item that should be included here.

Double-check that the features listed above are also disabled when disabling Hyper-V. Reference Microsoft documentation and the examples below to find out how each individual feature can be disabled.

Some platforms fail to immediately disable Hyper-V when it is switched off. When this occurs, there is no error returned by the Windows OS and Hyper-V appears disabled in the Windows Features Dialog. You can download and run this simple commandline cpuid utility to check whether Hyper-V is active. Please file a bug on Microsoft's issue tracker when this occurs.
