Both Python 2.5.2 and 2.7.2 flop the same way under Win 7

OK, I've found that. I see
Py
Pyc
Pyo
Pyw
If I click on each, it basically it gives a short description of each. 
If I click advanced, there's more info. For example for py, Actions are 
IDLE and Open.

What does this tell me that's relevant to Win7?

If on Win7, I go to Default Programs I see under associations various 
python items. Py shows Unknown application. Since installing 2.7.2 I 
have not messed with these associations. If I right-click on Unknown, I 
see Notepad and python.exe for choices to open the file. I want neither. 
Why isn't IDLE listed there?

If I right-click on junk.py, I see "Open with".  Notepad and python.exe 
are choices. However, that menu allows me to choose something else. For 
example, Adobe Reader, or Internet Explorer. I suppose the next question 
is should I use the browse there and try to connect to IDLE in 
...\Lib\idlelib?  My guess is that if I do, I will run into the "invalid 
Win32 app", when I try to use it.
