It seems a bit odd to me that I can’t access VM’s located on my local machine, especially when I’m a local administrator.
After looking around a bit, I found that there is a local Hyper-V Administrators group that by default is empty. Add yourself to the group by doing the following:
Access the Computer Management interface.
In Windows 7 and Windows 8, this can be found by simply searching for Computer Management.
Expand the Local Users and Groups section and click on Groups
Double click on the Hyper-V Administrators group
In the Dialogue box, click Add… and then enter your user name in the box and hit OK.
Hit OK again and close out of Computer Management
One more caveat. In my experience, I needed to log out and log back into Windows for the changes to work.
