Hyper-V : Error after removing VM

On browsing the Hyper-V Server Manager, I noticed some errors that I had not spotted before >

The Virtual Machines configuration (guid) at 'C:\hyper-V-Path\' is no longer accessible.

For some reason, my attempts at tidying up and moving the vm image files to a new location had not been 100% successful, leaving HyperV to periodically look for the image in the old location (despite the VM working fine from it's new location).

To rectify the situation, this technet post came in rather useful.

Basically >

1 ) Navigate to C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines (if you don't see anything, unhide files and folders via tools > folder options > view > 'show hidden files & folders')

2) Locate the link file that matches the GUID number in your original message.

3) In Hyper-V, click 'Stop Service' (turns off VMMS)

4) Delete the file

5) In Hyper-V, click 'Start Service' to restart the VMMS.

Errors should no longer appear every 2 minutes now.

Note : VMMS is the 'Virtual Machine Management service' and just controls your ability to manage VMs, they continue running even when VMMS has been shut down.
