Auto-typing passwords etc. into a Hyper-V guest is not working. What can I do?

Question

I am running several virtual machines (Windows and Linux) on a Hyper-V server.

I want to use Keepass to enter passwords stored on my local machine through the Hyper-V connection into the remote machines. As this includes Bitlocker PINs and Ubuntu FDE passwords, a simple Remote Desktop connection is out of the question.

However, the keystrokes are not recognized by the virtual machines. I tried Keepass, Autoit and AutoHotKey without success. It works fine with VirtualBox guests though.

What can I do?

Answer 1

This is probably caused by the fact that Hyper-V Manager is running elevated, so any program that has not been started as administrator can't interact with it.

Try running Keepass or your AHK/Autoit script as administrator.

Also make sure that the Hyper-V connection window is not in foreground when using the auto-type shortcut, as it will be forwarded to the virtual machine.
Either use a delay or configure Keepass to switch back to the last window before typing.
