You're ending up rerunning the installer - this seems to have been 
happening to quite a few Windows users recently.  The program you're 
launching is doing what it's intended to do - manage the Python 
_installation_, but it's not Python itself.

Try launching Python from the start menu - navigate to "Python 3.9" and 
start either "Python 3.9 (64-bit)" or "IDLE (Python 3.9 64-bit)" 
depending on whether you want the bare interpreter or the IDLE 
development environment,

or

 From a command shell type "py"  to activate the Python Launcher.
