As someone who makes a living off Windows software, surely you have paid for your license? Else you got absolutely no right to complain about anything breaking.
Actually, when you claim that it is not a free upgrade because you need to have paid for a valid license for the software you claim to be using, you are implying that you stole Windows.
The other poster appeared to be presuming that that implication was unintentional and inaccurate, and that the upgrade was indeed free for you.
