Or directly in the Cortana enter “Change Windows 10 Pro Product Key”
2. the Windows 10 Pro Product Key is: VK7JG-NPHTM-C97JM-9MPGT-3V66T
Your system will automatically start after upgrade to Windows 10 Pro (Professional Edition). Microsoft says that this applies only to the Windows Build 10586 10 Home Edition user.
Even more crucial is that upgrading is free, but, after entering the desktop that is needed to activate the professional version, buying into the “set” (Settings) “activate” (Activation) page, and then click the “store” (Go to Store).
Windows 10 Pro upgrade $ 199, $ 80 more expensive than Windows 10 Home.
