windows reactivation

[Alifac]

My laptop came with Windows 8 from the factory. I upgraded to windows 10 and now it's asking to reactivate windows. How do I reactivate windows with the factory key? I can't find the key number.

Hi:

Install the free Showkey plus app from the Microsoft Store.

Get ShowKeyPlus - Microsoft Store

Run the app, and it will show you the W8 OEM product key in your notebook's BIOS and the version of W8 the key is good for.

As long as you installed the same version of W10 (which should be W10 Home) that the W8 key was good for, you can change to the W8 OEM product key in the PC settings menu>Update & Security>Activation>Change product key.

Windows should activate afterward.
