Python virtualenv with Anaconda and python.org python 3.5

I have both anaconda Python 3.5 and Python 3.5 from python.org (on windows)

python -V
Python 3.5.1 :: Anaconda 4.0.0 (64-bit)

python3 -V
Python 3.5.1

py -V
Python 2.7.12

I want to create a virtualenv with only python 3.5.1 and not the anaconda version.

When I run

python3 c:\Python35\Tools\scripts\pyvenv.py venv

python -V still shows Python 3.5.1 :: Anaconda 4.0.0 (64-bit) after activating the environment

Is there anyway to get it to use the native 3.5 version?
