I have an Inspiron 7359 2-in-1 that crashed and was needed to change de motherboard.
How can I activate Microsoft Windows 10 that was bought with it?
Do you mean you got WIN10 with motherboard? I really don't understand, If is that, then you must have a License key with it, and that means in installation, they will tell you to activate windows, then put the serial key that was with the windows CD/USB. Well if you didn't get it (cause sometime happens), they will tell you to activate it, easily do it, and insert the serial key.
