I had a windows 8 singe language and it was originally installed with my new HP DV6 laptop and I wanted to upgrade it to the pro with media center and after it accepted my serial number and installed the updates and the laptop restarted, now it's showing in the action center that there is a problem with activating it. how can that happen? and now it's showing that I either put another serial number or start windows 8 setup
so how can I go back to like before so my old edition of windows 8?
Looking for tech help?
