Correct lookup of Explorer-specific file association information.

Browse Source 
The code added in r52154 never worked because it was looking for the Progid
value in a wrong place, look for it under UserChoice subkey where it really
is.

Also add a way to look up the command to open files with the given extension
to the exec sample.

Closes #12302.
