The installation process asks for zlib and I even setup & cloned it from Github. I\'m new to all of this.

On Windows, you're better off using precompiled binaries (wheels) than building from source.
Python 3.6.0 final is due out later this week on 2016-12-23 and Pillow does not yet support it. Hopefully it will be supported for the next quarterly release, on 1 January 2017.
However, in the meantime, you can download an unofficial wheel from here, then pip install filename.whl
