Hello Mr. WAWood, my heartiest thank for your answer. As you provide me the link I checked and it showed me the information as bellow:
But it doesn't solve my problem completely. I bought my laptop with a genuine version of Windows preinstalled. Now it should not be cracked or fake! If it is then I have to say HP and the retail shop has cheated me! Cause as far today I knew my windows was genuine. It has to be genuine cause I have paid for it. My windows have a license key too. So I think it is genuine and the notice about showing "your windows license will expire. . . . . . ..," is some kind of software problem. If there is another solution to this problem please let me know. Thanks a lot.
Good wishes from
