How to access installed scripts on Windows?

[ddbug]

Thank you eryk sun for the reply.

I am not so concerned by installing modules as by installing scripts ('entry points'). Per user.

If the Windows GUI installer can add the per-user script dirs to PATH it may be acceptable solution.

Is this the checkbox on the Advanced Options page, "Add Python to environment variables"?  
 
In my copy of 64-bit v3.6 installer this is UNchecked by default, and the text looks a bit vague. Might read more precise.

Interesting idea. But I have not seen any installers or guidance how to deploy something packaged as a venv to users. Can you share any pointers please?

I agree, but the current situation is dire IMHO. One of fundamental Python batteries is leaking :-(

Right now I'm looking at IDLE and trying to figure out whether it can be used to solve this problem (like, run IDLE with a special start script or extension that will make these user-local scripts easy discoverable .... Maybe a extension that adds a new GUI menu etc. )
