If i understand right you mean your COA sticker on your machine is unreadable, if so then you can retrieve your product key out of your system
Your key is stored in the registry but is encrypted so you will need a software solution to extract it for you

Please post an MGADiag report - the chances are that the Key reported by any KeyFinder application (such as Speccy/Belarc/MagicalJellyBean/etc) is going to be the OEM_SLP Key which is to all intents and purposes, useless to you.
The MGADiag will at least tell us which Key is in use, and will allow us to troubleshoot any current non-genuine message you are getting.
Please follow this tutorial and post an MGADiag report - then we can see what the problem is.
Please also state the Version and Edition of Windows quoted on your COA sticker (if you have one) on the case of your machine (or inside the battery compartment), but do NOT quote the Key on the sticker! http://www.microsoft.com/en-us/howtotell/Hardware.aspx
