pyw.exe (Python Launcher for Windows Version opens a console window at startup. To reproduce, run command below from the console:

D:>pyw -c "import time; time.sleep(10)"

By the way command:

D:>pythomw -c "import time; time.sleep(10)"

works as expected, silently.

I know what this is - in issue38133 I added support for the PEP 514 ExecutablePath key, but didn't add a check for WindowedExecutablePath for the pyw.exe case.

I'll add it.

This is resolved as far as I'm concerned - leaving open for Łukasz to cherrypick and close.
