Do you have a pointer where these locations are specified by Microsoft?

This would not only affect the config file but also the location of the
drift file and optionally the log files.
IIRC the current location below %PROGRAMFILES% had been chosen after a
discussion about the time when our first GUI installer was released.

Of course this can be discussed again and changed in future versions.
