I have a HP dv6 laptop which has come with original Windows 7 home premium 64 bit. The product key is on the sticker under the laptop. But, the sticker is faded away, so I cannot read all the characters (I can only read 10 characters out of 25). I tried two third-party software (Belarc, Magic jelly bean) which gave me product key that does NOT match with the sticker one.
How can I get the product key (the sticker one)?
P.S.: From the screenshot, it seems that my windows 7 installation is an OEM installation by HP. (correct me if I am wrong)
