Can't use Python Launcher on Windows after update to 3.5

I've installed 3.5 for all users so it's in C:\Program Files

 From it 
says "System-wide installations of Python 3.3 and later will put the 
launcher on your PATH. The launcher is compatible with all available 
versions of Python, so it does not matter which version is installed. To 
check that the launcher is available, execute the following command in 
Command Prompt:", but:-

C:\Users\Mark\Documents\MyPython>py -3.4
'py' is not recognized as an internal or external command,
operable program or batch file.

Further running ftype shows nothing for Python, assoc just gives this 
.pyproj=VisualStudio.Launcher.pyproj.14.0.  Surely this is wrong?

Before I go to the bug tracker to raise an issue could somebody please 
confirm what I'm seeing, thanks.

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
