None non-obsolete components at least.  That probably also applies to the VC
2008 runtime.

Which user?    I'm talking about osgeo4w.   There's a etc/ini/python-core.bat
in python-core (2) that makes python2 default if it's installed and that used
to be the default installed python.  py3_env.bat was added to switch from there
to python3.  If we were going to change that, the contents of py3_env.bat
should be moved to etc/ini - so that it's sourced by o4w_env.bat, which all the
batch files that start applications source.   The osgeo4w shell itself doesn't
use any python.

All of the above is osgeo4w and not QGIS.
