Hi.
Method 1:
Please click "Settings" > "Update and Security" > "Activation". If it is genuine, it will say "Windows is activated with a digital license".
Method 2:
Open cmd, type slmgr.vbs /dlv to display license information. In the pop-up window, if you see such information as Volume Activation Expiration, Renewal Interval, etc., then your Windows was activated with activation software and has been cracked. If it only shows the product key and license status etc., but no expiration time or anything, then Windows is genuine.
Hope the information is helpful.
