Use exec node in Node-RED while running Windows 10?

Question

I have been trying to run the exec node in Node-RED, hoping that it would use the command prompt native to Windows 10. I would provide a command that would run a python script I have. If the command went through, my windows button would be clicked. Node-RED says "Successfully Deployed" when I run my single exec node, but the windows button does not pop up. I am concluding that Node-RED does not know how to access the Windows command prompt, which is very frustrating. Is there a way to run python scripts from Node-RED while running Windows?

In case it is relevant, I am using Node-RED to communicate with the bluetooth low energy protocols of the Lightblue Bean Arduino board. I am sure that there is not a python library for communicating with bluetooth low energy for Windows. For Mac and Linux, sure, it's implemented by Adafruit. But they say they do not have anything for Windows.

Many thanks.

I asked someone and they told me you cannot have a standalone exec node- you need to use an inject node to get everything going. I checked off "Inject once at start?" and my script ran just dandy.
