These links aren't created by the installer, but you can create them
if that's your preference. Execute the following in an admin command
prompt:

    mklink C:\Python27\python2.7.exe C:\Python27\python.exe
    mklink C:\Python27\python2.exe C:\Python27\python.exe
    mklink C:\Python35\python3.5.exe C:\Python35\python.exe
    mklink C:\Python35\python3.exe C:\Python35\python.exe
