What are PATH and other environment variables, and how can I set or use them?
I know that I can edit my environment variables in windows 8 by going to
Start -> All Apps -> Control panel -> System -> Advanced System Settings -> Advanced -> Environment variables.
But honestly, this is ridiculously complex.
Is there an easier way to change environment variables in Windows 8?
For instance if I just want to append new folder to PATH, it is really annoying to go through all these steps. The UI also sucks, because it is really painful to edit long variable values with the small text input.
Requirement 1: I need the changes to persist (e.g. when I use
set in console the changes are lost when I close the console)
Requirement 2: I'd prefer a solution that doesn't involve installing extra pieces of software, since this is the kind of problem that I stumble across every time I configure a new Windows box.
