Guys I have purchased this laptop from hp store haridwar and everything was working fine but one day I received windows activation error that I needed to activate windows and my windows 10 is not genuine I was so shocked after I saw that message and after that my pc is become too slow and its too difficult to use it because it takes 10 minutes to fully open to use.
I contacted the dealer I told my issue and ask him my genuine windows dvd or key and he said sir there is not key or windows dvd. It comes only with backup which is already in your laptop you can restore it, I said if it was genuine then why I got error and he said I don't know ask hp.
Window 10 costs around 14000 inr and I think store guys sells those dvd differently to other customers who wants windows and and gets more profit.
It happened with me twice and they always says that company did not gave them cd or key they also uses fake windows activators to activate windows.
Hp should have clearly mention all the list of items that comes with laptop to avoid these type of problems.
