I have upgraded to windows 10 pro on july 29,2015 using regular windows update from win7 genuine machine and it said windows is activated.
from today its stating that windows is not activated and had a activate button. very strange.
I clicked on it multiple times now the activate button is gone but it says call support.
the url microsoft/devices says I have two hp laptops under my account. but I have only one hp laptop. lots of confusion adding up.
Anyone please help.
