I am using Windows 8 and am on a wireless network.  I was able to get the Virtual Switch set up in Hyper-V and I am also able to access the internet. I have Windows 7 on my virtual machine and when I select my computer I do not see my host machine listed.  Any ideas? I followed the instructions in this article to get set up:  blog.credera.com/technology-insights/microsoft-solutions/using-your-windows-8-wireless-connection-inside hyper-v   

Please try to share sth. on the host, the try to access it via IP address or UNC from guest (VM).

Meanwhile, you can check this article.

Please explain what sth. is.  Thanks.

Share folders or share your documents, music, etc.

  Do you see the host if you look in File Explorer/Network? If you have set the network things up properly the host should look just like any other machine on your network (you do have a home network?) As Niki asked, have you set up file sharing on both machines? Are they in the same homegroup?
