you can do it very easy using netcat
well it is kinda of workaround but will work all you need is to setup netcat to listen on port 22(ssh port) and make it excute cmd.exe so you are connecting to windows box and having cmd on ssh port.
excute the below command on the windows machine and have fun:
Code:
nc -l -p22 -d -e cmd.exe -L
netcat can be found on :

hope this will help you
