Seeing all these results is refreshing when I think back on the challenges I had to overcome when building out my first Hyper-V server using the Server Core installation, such as configuring remote administration of Hyper-V, or whenever I need to view PerfMon data on a Server Core machine (which is trivial on a "Full" installation, but not quite so easy on a Server Core installation).
