Hello,

I am receiving the following error when I try to start any virtual machine on Hyper-V Manager on a Windows 8.1 lap"color:black;">An error occurred while attempting to start the selected virtual machine(s):
Morillo-DC could not initialize (Virtual Machine ID …)

On the Event Viewer, I can see:

Thank you in advance for any help.
