Just found out I was taking up - and paying for - a lot of storage due to abandoned disks from long ago deleted VMs. I manged to delete most of them, but now I'm stuck with a set that cannot be deleted as they remain attached to VMs nowhere to be found.
Any ideas how to get rid of these disks, PowerShell tricks maybe?
If I am understanding correct, Once you delete a Virtual Machine, it delete the service but keep a copy of the VHD image under Disks. So please go to the Disks tab under virtual Machine and try to delete it.
If that is not the case, please add a screenshot with error message from where your trying to delete VM.
