Dusita Udomwongsa Posted November 2, 2021 Report Share Posted November 2, 2021 (edited) To whom it may concern, I could not deactivate from my old surface and could not activate my license to the new laptop. I am using Window 10 Pro on both machines. My serial number 234600-xxxxxx-397669. When I tried to deactivate from the old computer, I got -79:Activation Error. When I tried to install on the new computer, it said I need to deactivate first. Would you please help? If you need further information, please let me know. Thank you very much in advance.
