What would be a good price to charge to downgrade windows 8/10 to 7?
How much money would you charge on top of a license?

Not quite sure of what you are asking is this something you are doing for someone else because in this forum really isn't the place to ask about recompense for helping someone out.
I personally will do things for nothing except charge for parts of course (if those parts are reasonably pricy) and I have to incur a cost of new part/s and I just like the challenge of doing whatever is being asked for.
