Obviously putty is one (of several) terminal emulators (or in short gui 
clients) for ssh protocol. This means they are made for interactive work
with mouse and keyboard rather then for command automation.

Its easy if you just use one of the many command line ssh clients. You
can use os.popen() and friends or the command module to work with them.

There is also another solution:

which implements the ssh protocol in python so you can do more and
have finer control over the processes and channels (for example
file transfer and command control w/o resort to multiple connections)

This is a little bit harder of course.

Also, sometimes its more easy and relieable to just use cron on unix 
side. This works much much better then Task scheduler on windows btw.
