In Windows OS, what is the best method of loading a python script on boot-up and then reloading that script after it's conclusion?

Question

In the MS Windows operating system, what is the best way to start a Python script on OS start, and keep restarting that script when it (the script) ends? In Linux, I have defined a service in /usr/lib/systemd/system/myScript.service that does this. A portion of this script is below,

[Service]
Type=simple
ExecStart=/usr/local/bin/myScript/myScript.py
Restart=always

I'd like the same functionality for the windows box. I suspect the windows versions that will be used are more the recent 64-bit versions (Win7 or later).
