Hi
While it is obvious that you are upset about something, I cannot make head and tail what it is about.
In the first paragraph, you are complaining about what looks like a problem with the product key.
In the second paragraph you want to reset the Internet connection, I do not know what it means to reset Internet connection in the computer, usually rebooting the modem and the Router the connection.
Please post what exactly is not working, and what do you want to achieve.
