Welcome to JustAnswer. My name is Bryan and I will be assisting you today. Please do not rate this session until it has been completed.
Can you clarify what you are looking for? I don't understand what you are asking for to unlock the product key.
I purchased a new cpu which has Windows 8 installed and it tells me to activate windows and it shows me the last 5 digits of a product key says "current product key xxxxx-xxxxx-xxxxx-xxxxx-CYQG3
Ok. So you need to activate it. Give me just a minute to get the steps for you.
Actually, this site has a good tutorial on how to activate it. You will need your full key though. Do you have that?
No, only the last 5 digits, as cpu was already installed with Windows 8
There should be a sticker on the case of the computer, normally on the bottom (if it's a laptop), or the back (for desktops and tablets). That sticker will show your product key. If it's not attached to the case, it may be underneath the battery (if it's a laptop).
If you don't have it, try going through the activation routine anyway. It may be embedded in the BIOS and the activation routine will read it automatically.
Very good. Yeah, they do print them kinda' small. And watch out for those 8 and B differences ... those have fouled me up more than once.
Alright, well let me know if you need anything else. I'll be around. :) Otherwise, take care.
