Windows 10: enable/disable Hyper-V from CLI

Reading time: < 1 minute Assuming we're running a Windows shell with administrator privileges, using next commands is possible to enable, or disable, Hyper-V.

I require Microsoft VM manager Hyper-V because I also run Docker for Windows and it's a requirement.

#enable Hyper-V
dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All

#disable Hyper-V
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
