Not sure why this occurred however I was planning to add a new drive to a vm, however could not add the new drive.

Thinking back to an issue with a VM at work, on my VM exchange I tried to edit an existing drive on the VM and it mentions checkpoints exist.

In poweshell I did get-vmsnapshot Exchange it mentioned it was a recovery checkpoint

The command I used to remove it was get-vmsnapshot exchange | remove-vmsnapshot

Below is a screenshot of the CMD/Powershell window
