Portable Python Versions

Coding Python Support
1

so I tried out bot WINPYTHON and PORTABLE PYTHON (google them) both of these are supposed to be able to run from a flash drive
WINPython only worked on one of my 3 computers in which i tested it on…
Now PORTABLE PYTHON seems to actually work on all of my computerrs that i tested it on however, every time i stick my usb into another computer, it forgets what program to initialize for running my .py file type. So basically, every time i want to run a script on a new computer, i have re-select the PORTABLE PYTHON.exe for “opens with” in my script’s properties.
2 questions:

1 is there a way to get my scripts to automaticly run using “PORTABLE PYTHON.exe” on my flash drive?

2 ive installed just “regular” python on my usb flash drive before and it worked, so really…whats the point of these portable versions of python?

portable means you don’t need to install something to run it, but it doesn’t necessarily mean it will integrate with OS (seems like OS doesn’t store file type associations if the app is on a removable drive - which is quite reasonable)

why do you need a portable python in the first place, blender comes with built-in python and should be fully portable?!

Basically, I want to have PYTHON in a flolder on my flash drive so that I can run each of my scripts on my flash drive at will. The problem is that my python scripts (.py) depend on the operating system registry in order to tell what program to run them with.
