Windows 7 Sticker is unreadable! (I can see 17 characters)

[nikolaidisdd]

Hey there people,

as you can see on the title, I have a laptop "HP 620 Notebook PC" that the stick with the Windows 7 Product Key, is not visible anymore. (Actually not personal laptop, but my wife's sister laptop).

The installed windows (there are in the laptop right now) is not the Pre-Installed Windows that the Laptop had in the first day but other windows who a Serviceman installed before some years. That means, even if I use software to get the Product key, I wont get the "real" product key, but pirate product key that someone installed on this laptop before some years.

Nowadays I decide to install the Windows from the sticker, but unfortunately I'm not able to see the characters.

I'm able to see about 16~18 characters (or even 20) but the rest are half visible and even if I tried to make combinations looking on the "edges" of the letters, ..I lost!

Is there 

Is there any way to recover my product key with S/N of Laptop by communicate with HP/Microsoft Support, or probably noone will help me?

Thank you in advance, Dimitrios.

Unfortunately NO -- MS has no way of recovering it, and HP keeps no records of individual product keys associated with individual PCs.

Furthermore, any key retrieval tool is only going to display what is already there, and if that is indeed a "pirate" key, that is all you are going to be able to see.
