  Currently, since there is no runtime directory set, the code tries to
create a file in C:\ which is only writable with administrator
privileges. As a result, if the user is not admin, the application will
fail.
So, forcing no_shconf to 1 to prevent the code having to create files in
the runtime directory.

This is the correct way, as in-memory implies no_shconf. I would like to 
deprecate noshconf option as it's a subset of what in-memory does.
