windows - Change the version of Python that runs by default

Question

I have two versions of python installed in my pc:

and:

when I type in cmd 'python', the version executed is 3.7.1 32 bits, and all my projects run on that version, which caused me problems when trying to install the pyarrow library. I would like my projects to run on the 64-bit version. Is it possible to change the default versions on which I run python? I cannot delete the 32-bit version, as I do not have administrator access.
