I just manually set my path within the same command prompt.
I tried editing the environment variables through the UI and adding the paths to pyenv-win/bin and pyenv-win/shims (lines 99-100) but that still didn't work.
If it isn't much trouble, could you share the command that you ran in the command prompt to set your path?
What location did you add to PATH? @the4amfriend

I have the same problem and am quite new to windows. Could use a pointer her too :)
