Some of my VMs run Hyper-V themselves, of course, as I'm using Docker for Windows and WSL for development in these VMs. But I've configured all my VMs to use all virtualization options there are:

Strange, though, that the most simple VMs I set up (de-de_windows_10_enterprise_ltsc_2021_x64_dvd_71796d33.iso, nothing else installed, just using Microsoft Edge) are slow and cumbersome.
