Under Administrative Tools there is a program called Hyper-V Manager. You can create and manage VMs from there. In the event that you're running a Server Core install instead of a full GUI install then you'll have to configure the server to allow remote management, then install the Hyper-V Manager on another computer (downloadable from Microsoft) connect to your Hyper-V server remotely.
