Error starting a windows slave from a linux master over SSH

[Badal]

Hi,
my jenkins master is running  on Linux.
Slave is on a windows server that has freeSSH installed. I have a freeSSH user created and named as "jenkinslave". I can successfully SSH from the Linux box to the windows slave.
Windows does not have Cygwin.
 
I am trying to start the slave from the Linux with the "Launch slave agents on Unix machines via SSH " launch method as I did not see any option to start windows slave via SSH. I would like to start slave over SSH as the windows service option has some limitations for GUI test. I would like to stay away from Cygwin as it is heavy. I am not sure if Cyqwin is a must requirement or not.

When master tries to launch the slave I get the following error. The credential used is the private key for "jenkinslave".

SSH connection reports a garbage before a command execution.
Check your .bashrc, .profile, and so on to make sure it is quiet.
The received junk text is as follows:

Any help is appreciated.
