We went to Settings -> Update & Security -> Activation – > Enter Product Key and copy/pasted our Windows 10 Professional license keys there.Īfter a couple of seconds, Windows 10 connected to Microsoft servers and verified our keys as valid and voilà – Windows was activated for less than $5, quite different from $90 which is what Microsoft sells it for.īoth machines were activated and working… Keys arrived via eBay message system within two hours.
