It's easy enough to remove those references.

Try to start Python 3.5 to check that it's really gone:

C:\> py -3.5

It should complain if it's no longer there.

Start Python 3.6:

C:\> py -3.6

Have a look at the references to Python 3.5 in the PATH environment 
variable to double-check:

 >>> import os
 >>> [p for p in os.environ['PATH'].split(';') if 'Python35' in p]

Remove those references from the PATH environment variable:

 >>> os.environ['PATH'] = ';'.join(p for p in 
os.environ['PATH'].split(';') if 'Python35' not in p)

Job done!
