Hyper-V may be preferred  to run Windows virtual machines due to its excellent 2D graphics performance and disk performance. Hyper-V is also necessary to develop Windows Phone applications.

 

Problem

  • Slow games or 3D applications when Hyper-V is installed.
  • Using alternative virtualization software to Hyper-V. (In some cases you need to have VMWare Player installed for example to uninstall VMWare Tools to make it Hyper-V compatible.)
  • Dual boot is not an efficient solution.

 

Requirements

- Windows 8/8.1 (for this guide)

- Hyper-V installed

 

Solution (Recommended)

  1. Install Hyper-V.
    Go to 'Control Panel'.
    Select 'Programs & Features'.
    Now choose 'Turn Windows features on or off'.

  2.  Open 'Command Prompt' as an administrator by right-clicking the start orb or the bottom left corner of your screen.

  3. Now enter:
    bcdedit /copy {current} /d "Windows 8.1 (Without Hyper-V)"

    The above command will copy your current boot entry into a new one using the name entered after the '/d' option. You can change that to something else if you want.

  4. Restart your computer.

  5. Make sure to start your computer using the boot entry you just added in 'Step 3'.

  6. Open 'Command Prompt' again as an administrator as described in 'Step 2'.

    Enter the command below to disable 'Hyper-V' for that boot entry:
    bcdedit /set {current} hypervisorlaunchtype off

  7. Restart your computer, and start the new boot entry again you created in 'Step 3'. We will verify in the next step that Hyper-V is disabled for the new boot entry.

  8. Open 'Command Prompt' as an administrator again, and enter 'bcdedit' (without quotes). Find the entry where the identifier says '{current}'. Verify 'hypervisorlaunchtype' is set to 'off' for that entry.

  9. You can now attempt to start alternative virtualization software on the boot entry we just created. If you want to use Hyper-V you can always use the other boot entry.

 

 

 

Please note. Hyper V option is only available to users who are running Windows 8/8.1 Pro or Enterprise editions
