After I upgraded my workstation to Windows 10,  I am no longer able to power on guest OS on VMware operating system and received error as below

‘VMware Workstation and Hyper-V are not compatible. Remove the Hyper-V role from the system before running VMware Workstation’

After some searching, I found that it is caused by ‘hypervisorlaunchtype’ on windows loader is set to ‘Auto’.

Disable Hyper-V


To disable Hyper-V role, follow the steps below

  •  Open ‘cmd’ prompt with elevated privileges i.e.) with Administrator access
  • To disable Hyper-V, run following command
bcdedit /set hypervisorlaunchtype off
  • Restart computer

Enable Hyper-V


To enable Hyper-V, follow the steps below

  •  Open ‘cmd’ prompt with elevated privileges i.e.) with Administrator access
  • To disable Hyper-V, run following command
bcdedit /set hypervisorlaunchtype auto
  • Restart computer
