Hyper-V Password Problem

I installed Windows 10 in Hyper-V and now I can't log-in. I tried deleting the first VM and reinstalling which led me to calling MS to reactivate. Now it's doing it again. I have the log-in screen but no option to type in my password. Is there a way for me to fix this without reinstalling? If I understood the tech correctly, I can only use the key three times.

I managed to log-in. There is an option in Hyper-V to use a Basic Session. When I clicked on it the VM restarted and I had the sign-in box. Does anyone know what I need to do to be able to sign in normally? I'm not going to mark this as solved because it's only half solved.

This is a known problem, with a known solution from Kari.

The problem is, that Enhanced Mode in Hyper-V is based on Remote Desktop Protocol (RDP), basically exactly the same than a remote desktop connection. RDP requires a password sign-in, it does not accept PIN. As W11 OOBE / setup, when user uses an MS account, requires user to create a PIN, and enforces Windows Hello at sign-in by default, Hyper-V VM enhanced mode sign-in fails, only showing an empty screen. The system is awaiting a PIN as Windows Hello has disabled password sign-in. PIN is not allowed becase of the remote desktop protocol, system cannot show sign-in screen.

The solution really is simple. Sign in once in normal mode, disable Windows Hello enforcement, and switch to enhanced mode. Sign-in screen will be shown, and user can sign in to VM with password.

Trying to install Windows 11 in Hyper-V problem - post #9


Edit: actually that reply from Kari was to a post by you, so you seem to have forgotten his advice

I did forget about the time I was trying to run Win 11 Home in a Hyper-V and couldn't get the sound working. Turning off Windows Hello did work. For some reason it took two restarts after turning off Windows Hello before I could get the Win 10 Pro VM to do 1920 X 1080 even though Hyper-V was full screen. One thing that was has me confused is that when I installed Win 10 everything worked. It wasn't until after a couple of restarts that I lost the sign-in box. I tried removing the first VM and starting over. The second install was working except it wouldn't activate. When I called MS, I had a very long wait until I reached a tech. I had to give them a very long ID number and they gave me a new ID number to enter. After Win 10 was activated, they wanted me to do a couple of restarts. The second restart was when I lost the sign-in box again. He transferred me to another tech who didn't know what to do. They suggested that I do another clean install. Not wanting to go through the hassle of reactivaing again I told them I would ask for help from the members on ElevenForums.

MS surprised me tonight. They called me to see if I was still having a problem. I told them my problem was solved and that I'm once again a very happy Windows user.
