where (latest Win10): in the control panel, System and Security, System, 
Advanced system settings (left edge menu item), Advanced Tab, 
Environment Variables (button).

Two sets of variables. User should always be able to set User variables 
that are in effect for all new processes launched after creation of the 
variable. System variables may be locked down if not administrator.

Both types are permanent, stored in the registry.

 From a command line, batch file, or program launcher, temporary, local 
environment variables can be set that only apply to other programs in 
that session and that session's child processes.

So there is no fear of being unable to set an environment variable on 
Windows. Naturally, some users may not know what they are or how to set 
them, but it is well-documented in various places... just google "how to 
set windows environment variables".
