Not sure if I can classify this under Boinc, as it's an SSH question,
I use SSH to connect to other PCs, but with one of my PCs I got this message:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
SHA256:*************Some Key Here****************.
Please contact your system administrator.
Add correct host key in C:\\Users\\creat/.ssh/known_hosts to get rid of this message.
Offending RSA key in C:\\Users\\creat/.ssh/known_hosts:5
RSA host key for 192.168.0.1 has changed and you have requested strict checking.
Host key verification failed.

I was wondering how to reset the key in Windows CMD or Powershell?
Some webpages recommend editing the RegEditor, but only when Putty is installed.
I don't run Putty.
What options do I have to reset the key?

May be a stupid thing, because the address is actually from my router.
