Windows 10 up grading to w10

[nichosi]

Hi,

Some time ago I was prompted to get w10 pro 64bit Insider for free, eventually I downloaded it on a USB stick & eventually I updated my W8.1 to w10.

I do not remember if I needed activation product key for this free Windows 10 Insider , I only have the w8.1 one.

I tried to up grate my laptop W8.1 to w10 & it asks to enter the 25 digits product key.

How do I go about this installation?

Get the media creation tool and use that to upgrade.
