Hi @EMP_H ,
Yes, you should be able to switch between python versions. As a standard, it is recommended to use the python3 command or python3.7 to select a specific version. The py.exe launcher will automatically select the most recent version of Python you've installed. You can also use commands like py -3.7 to select a particular version, or py --list to see which versions can be used. HOWEVER, the py.exe launcher will only work if you are using a version of Python installed from python.org. When you install Python from the Microsoft Store, the py command is not included. Since you're using the Microsoft Store version of Python, you should use the python3 (or python3.7) command.
Hope that helped. Please let us know if you have further questions.
Best,
