Python 3.9 WINDOWS 10 PATH

Hi all,
I am trying to troubleshoot/modify my python interpreter. I have downloaded 3.9, but my environment variable still points to the original 3.8 directory. I use ATOM (on occassion) and the CMD to run my little scripts.

  1. If I change the path in “C:\Program Files(X86)\Common Files…” to the new 3.9 directory, does that “break” the CMD path? I’m worried once I remove the 3.8 directory, I will lose ATOM connectivity.
  2. Why does the environment variable have a special variable called, “Python_Home”? Which does point to “C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Python 3.8” Is this the link that runs my ATOM scripts?
    Thanks for any help.

@datafiend You have to change the PATH system variable. Here is what it looks like.


Change the Python38 to Python39.
