Microsoft said that pirated/unauthorized/non-authorized Windows users can also upgrade to Windows 10, but the unlicensed version will not get genuine Windows 10, there will be a watermark and reminder to purchase genuine license, that is, you can also use Win10, just a watermark, fortunately just a watermark, not a black screen.

If your previous Windows has not been activated by Geniune, then if you upgrade to win10, you will be pirated. The desktop will always display a message indicating that the system is not authorized. This can also prompt the dealer whether it is a genuine system. At the same time, it is reminded that non-genuine Windows 10 systems will be more vulnerable to attacks and malware infection risks.
