How to switch from basic session mode to enhanced session mode on a Hyper-V virtual machine?

I’m working with some virtual machines, using Hyper-V technology.

Apparently, the speed with which files are copied back and forth might depend on the kind of session mode (basic or enhanced).

When I log onto my virtual machine, I get the opportunity to enter username and password and I’m logged in a basic session mode.

When I click on the keyboard button in order to go to enhanced session mode, the screen asks me to press Ctrl+Alt+Del but when I do that, I see the “Control/Alt/Delete” behaviour on my main machine. Here a screenshot of what my virtual machine looks like:

How can I proceed?
