I have the identical problem that everyone else is reporting. Bootcamp is working fine. Parallels 10 is not activated. Tapping Change Product Code freezes the Settings app. Parallels is a fairly big market for Microsoft so please work with them and solve this problem for your customers.
I tapped on the Go to Store button, the top of the page initially said that something went wrong and to try again. I tapped the button and it then said that my Windows is genuine. Settings still says it is not activated though.
Why does Settings freeze when you tap the "Change product key" button?
Why does Settings not show a phone number for activation as the Microsoft web site says it should for Windows 10?
Why does the Microsoft Store say that Windows is genuine but Settings say it is not activated?
How long do we have to fix this before Windows will refuse to run?
