SecurAble is a tiny utility/app will tell you if your processor has a hardware virtualization, which is what Hyper-V requires.   Even though most new processors nowadays have hardware virtualization, there are some Intel Xeon based cpu’s that are only a couple years old that do not. 

You can check this website for the download link and additional information:
