saving credentials with cmdkey #462

I am trying to store logon credentials for sshfs using windows cmdkey command.

cmdkey /generic:\sshfs\user@mysite.com /user:user /pass:password

The cmdkey command works fine and I see the stored credentials in credential manager.
However, I can't connect to the sshfs file system using net use without a userid and password
The only way I can get windows to store the credentials correctly is interactively in windows file explorer and ticking off the "remember" checkbox.

Would like a command line solution if possible.
