dude..the most important aspect of using unlicensed software is you are stealing other people's hardwork. I am not saying that you must use licensed or not but at least know that you are doing something illegal. The choice is up to you.

And BTW you are late by 2 days. The free windows 10 is already closed since 31 july. Else you could install windows 7 and then run the free windows 10 upgrade.
