I have installed OpenSSH server and client on a windows 10 laptop. It wasn't working, so I unistalled and reinstalled both, then it was working fine. I could ssh into my windows machine from other machines on the same local network using windows username and password to authenticate.
Then, according to
https://www.hanselman.com/blog/the-easy-way-how-to-ssh-into-bash-and-wsl2-on-windows-10-from-an-external-machine
, I changed a registry key to change the default shell to bash.exe ( wsl2 is installed on my windows laptop )
So, I typed this in a powershell: New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\WINDOWS\System32\bash.exe" -PropertyType String -Force
and after that I could not ssh anymore to my windows laptop, getting this error message: PS C:\Users\cedric> ssh cedric@192.168.0.16 ssh_exchange_identification: read: Connection reset by peer
I've tried to change back the openssh shell registrey key like this and I still got the same error message: New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -PropertyType String -Force
I've also unistalled and reinstalled both Openssh client and server, restarted the laptop and I still get the error message when attempting a ssh connection to the windows laptop: ssh_exchange_identification: read: Connection reset by peer
Finally using verbose option, here is the detailed output: PS C:\Users\cedric> ssh cedric@192.168.0.16 -v OpenSSH_7.5p1, OpenSSL 1.0.2k 26 Jan 2017

Is there anything I can do to make ssh server work again on windows 10 ? Thanks in advance for your help
