New submission from Terry J. Reedy <tjre...@udel.edu>:

Python Setup and Usage, 3.3.1. Excursus: Setting environment variables
https://docs.python.org/3/using/windows.html#excursus-setting-environment-variables

The word 'excursus' is so rare and archaic that this is my first encounter with 
it.  Could we drop it?

The last paragraph starts with "To permanently modify the default environment 
variables, click Start and search for ‘edit environment variables’,".  This 
part is fine on Windows 10 as it brings up "Edit the system environment 
variables" and "Edit environmental variables for your account".  Both take one 
to an Environmental variables dialog.  The former requires than one be or 
become an admin user (via UAC dialog). 

The paragraph continues "or open System properties, Advanced system settings 
and click the Environment Variables button. In this dialog, you can add or 
modify User and System variables. To change System variables, you need 
non-restricted access to your machine (i.e. Administrator rights)."

On Windows 10, at least, this is confusing or wrong.  Control Panel has 
'System' linked to the System dialog.  This has 'Advanced systems settings' 
linked to System Properties, but one only get there by being or becoming (via 
UAC) an admin user.  This has the  Environmental Properties button mentioned 
above.  It opens Environmental Variables for the admin user you are or are 
acting as.  This route cannot change EVs for non-admin users.  I have the 
impression that this has changed since Win 7.
