How to establish the primary and secondary monitors via MS Windows Registry

Question

I would like to establish the primary and secondary monitors via MS Windows Registry and later to change their number.

I mean to make secondary monitor as primary and vise versa.

I have tried to search here but no joy. Any clue?

Windows Registry Editor Version 5.00
