By "use windows console" do you mean "M-x shell" inside Emacs?  Or do
you mean something else?

You mean, you install new stuff into a newly created directory, and
then add that new directory to PATH, is that right?  Or do you mean
you put the new stuff into an already existing directory that is on

Please describe how you change PATH (if that's what you do), exactly.
When I change PATH via "My Computer" (or maybe it's called "Computer"
on your system), restarting Emacs does capture the change.  But maybe
I don't understand what is it that does not work in your case.  I
suggest to describe the issue in more detail.

In general, there's no way I know of to change PATH inside a running
program (in this case Emacs), except by restarting it.  Of course,
since you have a shell running inside Emacs, you could just modify
PATH from that shell's prompt, or run a batch file prepared outside of
Emacs to do that.

Not sure what this means: are you using one of the methods described
in that article to modify PATH?
