VMs running "on" Windows 10? That would make Windows 10 your host, not your guest. For now I'll assume that you've given me bad information, and move you to "Linux Guests".

You ran the zero fill tool in the guest right? Because obviously, running it on the host is going to do nothing for a guest filesystem. Except now you'd have to clarify how you managed to run sdelete in a Linux guest.

You mean the host? We are discussing the configuration of a virtual machine, the technology used by your physical host is not directly relevant. VirtualBox doesn't require the presence of a physical SSD in order to simulate a virtual one.

Yes, you could clone to an external drive or network folder.
