VMWare Player is not working after installing Hyper-V on windows 8 Pro

I was using BB10 simulator on windows 8 but last night I installed windows Phone 8 development environment and it also installed Hyper-V (or activated it). Now I am unable to run BB10 simulator in VMWare Player. Wondering how I can run them both at the same time or both on the same machine?

Solution 1:

I have got a solution. This method will allow me use one technology at a time (which is my current requirement)

You can disable Hyper-V without uninstalling it. Start a command prompt with administrator rights and execute the following command:

// to disable hyper-v
bcdedit /set hypervisorlaunchtype off

// to enable hyper-v
bcdedit /set hypervisorlaunchtype auto

Both Operations require restarting your computer.

Note: I also found this very helpful when using intel x86 android emulator because without this, it was not possible to use it.

Solution 2:

An alternative solution that worked for me, using the UI rather than the command prompt:

1. Search for and open the "Turn Windows features on or off" window.
2. Toggle the checkbox next to "Hyper-V".
3. Restart.

Both caveats still apply here: Only one technology can be used at a time, and a Windows restart is required to switch between them.
