What it means – "Register Anaconda as my default Python"?

  anaconda, installation, miniconda, python, windows

During installation process (Windows OS) I have 2 options:

  • Add Miniconda to my PATH environment variable
  • Register Miniconda as my default Python

The first option is pretty obvious. I understand it completely.
But what about the second? What is meant by the word "register"?

It creates the file with the string "Ok I have registered your Python"or what? What specific operations will be performed?
It’s so confusing. I have read the whole documentation on their site, but I couldn’t find anything about this.
