I did my first Hyper V installation a couple years ago. After setting up the VM I created a snapshot thinking that it was a way to freeze it in case it messed something up and go back to it. Now - I finally figured out that it created an AVHD and it's been growing in the background for years. Now I have a 600 GB VHD and a 1.6 GB AVHD. There is only one snapshot dated 6/2012. The hard drive it's on only has 60GB of space left on it. The question is: How do I get rid of that snapshot and get the disk space freed back up? I've included a screenshot of the files and the Hyper V screen.
