i want to get a new mobo will i have to repurchace windows?



i did read it and what i understand is that i got to make a Microsoft account and put with windows 10 on my account? correct?
do i have to de activiate it on this current mobo?
 


Correct.
And there is no "deactivation". Just follow the steps, and with the new hardware, go through the activation troubleshooter.
