Windows 10: Powershell breaks with semicolons in the PATH environment variable

I've been going down a rabbit hole with how Powershell processes the PATH environment variable. I am developing a program that helps manage the PATH, and I recently discovered that it has issues when a path containing semicolons is added to the PATH.According to [this comment on Github]https://github.com/HorridModz/Flow.Launcher.Plugin.Add2Path/pull/8#issuecomment-2596593503 by another user, Powershell interprets the PATH by splitting using the delimiter, which is a semicolon. However, it interprets quotes literally.This is a problem, because adding a folder path that contains a semicol

It looks as though you could simply define $INCLUDE as you wish.


Then there's pathed which appears to support including semicolon separated lists.

System environment variable won't stick

Running Win10 Home on an Acer Spin 3, 64bit, i7cpu. I try to add a path to the system environment variables by:

1. Control Panel > System > Advanced system settings > Advanced tab > Environment variables

2. The "Environment Variables" window opens.
3. In the "System Variables" pane I select "Path" and click the EDIT button.
4. A list of the current system paths is displayed.
5. I click the NEW button, browse to the path I want to add which is "C:\Python36-32" and click OK. The path "C:\Python36-32" is added to the list of current system paths.
6. I click OK and am returned to the "Environment Variables" window.
7. I click the "X" at the top right to close the "Environment Variables" window.

Now if I click the "Environment Variables" button again (end of step-1) and repeat steps 2-4, the new path I added in step-5 is gone. IOW, adding a new path won't stick.

What am I doing wrong?

 

Environment variable troubles

Well, I need to add a new environment variable to PATH and I have tried to do so through the GUI and PowerShell command lines. However even after I've done this PowerShell and Cmd both can't find the variable and end up redirecting me to the Microsoft store. The variable is a python executable for further elaboration. The path does show up in the PATH environment variables GUI but for whatever reason the system can't find it. Any help is greatly appreciated.
