"Edit with IDLE" doesn't work any more ?

[Yip, Kin]

Hi,

I'm relatively new with Python3 in Windows 7.  I'm using now Python 3.6.1.

Suddenly right-clicking on a .py file  and choose "Edit with IDLE" just doesn't work.

I've tried to do :

"c:\program files\python36\pythonw.exe"   -m idlelib    mypythoncodes.py


the IDLE editor just doesn't come up.    But if I start the IDLE Shell and then "Open File", the editor is there and
works normally.

I've tried to uninstall "python launcher" and then repair or modify  "python3.6 " in Control Panel/Program and Features.   Nothing works ...

Any help ?  I show you my Windows registry at the bottom of this email.
