mshv-overview

As a Systems Administrator, if you use the Microsoft Windows Server Hyper-V technology to run virtual servers, then you’ll probably want to memorize these commands.

If you know you don’t need to run any virtual servers, you can disable Hyper-V to gain some performance. Then you can re-enable it later. This is very useful if you have a test environment or lab.

To Turn Hyper-V off, Run this command then restart your computer:
bcdedit /set hypervisorlaunchtype off

To turn Hyper-V back on, run this command then restart your computer:

bcdedit /set hypervisorlaunchtype on (or auto start)
