Cannot delete checkpoint: Access is denied. (0x80070005). Virtual machine failed to generate VHD tree. Failed to get VHD parent.

Hi @kangarooo,

Multipass only guarantees support for changing settings of vms as we provide access to them (see modifying an instance), so we cannot predict the behavior of Multipass after changing the settings of a vm through the Hyper-V Manager. I tried setting a vm launched through Multipass to dynamic memory and had no problems, but it may not work for you.

As for the issue you described with not being able to uninstall and/or files not being removed after uninstalling, I believe it is being tracked with #3337.

Then, for the checkpoint error. Normally, you should not be encountered this as Multipass is not designed with having the user change things in Hyper-V Manager in mind. This is also a non-issue in Multipass 1.13 which is scheduled to launch in the near future. In the meantime, I would suggest trying to delete-purge the instance and launching a new one.
