Installed this on my HP laptop about a week ago, everything went fine, has been updating and running smoothly since.
Came home today and it did a window's update, Now it says I will need to reactivate Windows 10 with a new activation key?
Not sure why it's doing this, or how I can re activate it, it was working fine...
If i can't use window's update then that's not a very good release in my opinion.
