When the installation is complete, you are prompted for a long password for the administrator account, and then a screen like the Server Core mode opens with 2 command-line windows on an empty desktop.

You can not install additional operating systems from this interface. However, you can perform some basic service tasks-for example, join a workgroup or a domain, assign a computer name, set basic network settings, add a local administrator account, configure the Windows Update service, set up a remote desktop, set regional and language options, Date and time. To actually install and manage virtual machines, you must use Hyper-V Manager (or another tool, for example System Center Virtual Machine Manager 2008) from another computer or server.
