Hyper-V Config 4096 Error

In my case it was old references to removed VMs on my Hyper-V host: 

"The Virtual Machines configuration DC6D0B26-9438-4504-9500-73342A42EC0B at 'E:\UTIL02-VM' is no longer accessible: The system cannot find the path specified. (0x80070003)"

So, I just delete configuration reference XML file  "DC6D0B26-9438-4504-9500-73342A42EC0B.xml" from: 

"C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines"

But be careful, do not delete valid reference!
