UPDATING FROM WINDOWS 10 HOME:

Disconnect your internet connection for the following process!

1. Open the Settings app through the start menu (or the home page in tablet mode) and select the Update and Security category.

2. Select Activation and then click on the Change Product Key button. Enter the generic Windows 10 Pro key VK7JG-NPHTM-C97JM-9MPGT-3V66T. This key converts Windows 10 Home into Windows 10 Pro.

3. After restarting to upgrade to Windows 10 Pro, the operating system is no longer activated. Then, enter the valid Windows 10 Pro key for activation.

4. In some cases, the update may abort at 100% with an error. If that happens, manually restart and your system will have been upgraded to Windows 10 Pro. You can now activate it with the provided key.
