    information   Information
    This tutorial will show you how to enable and disable the built-in Hyper Virtualisation (Hyper-V) feature in Windows 8 Pro or Windows 8 Enterprise.

    Hi SirDarknight,

    Welcome to the forums

    Hyper-V is the built-in hypervisor for Windows 8/8.1 Pro and Enterprise Edition, the technology is also part of Windows Server. It gives you the ability to run multiple operating system on your computer at one time using virtual machines.

    You can read in the notes Bringing Hyper-V to "Windows 8" and the following Wikipedia page for more information Hyper-V - Wikipedia, the free encyclopedia

    I hope that helps, any more questions please ask.

    Cheers,
    Harry

    Another tip is to make a new boot entry. You can then choose on reboot whether to boot with Hyper V turned on or not.

    This is very useful as if Hyper V is installed then VirtualBox or VMWare will not work. Nor will the phone emulators in Visual Studio. You get a message VT-x is not available (as Hyper-V is using it).

    1. Install Hyper V as in the tutorial.
    2. bcdedit /copy "{current}" /d "Hyper-V"
    3. bcdedit /set "{current}" hypervisorlaunchtype off

    Then you can choose when you boot if you want Hyper V or not so if you want to use virtual Box for example you pick the boot option without Hyper V.

    Hello Tony,

    Enabling or Disabling the Hyper-V feature alone doesn't use any more space since it's already included in Windows 8/8.1 Pro/Enterprise.
