Windows 10: Not activated

So I had the preview build, after windows 10 was officially released I was told all I had to do was install Windows 10 final version and skip when it asked for a serial. Checking everything, it has activated at all.

I tried this with my windows tablet same process other than coming for a preview build I was coming from Windows 8.1 and it was activated when I installed windows 10 final version.

Any help is appreciated. Thanks

Windows 7 came preinstalled on my computer, how do I find the product key?

The product key is usually located on the COA sticker attached to the bottom of your laptop or in the battery compartment. In some rare cases it can also be found in the memory compartment. For tower systems, look at the top or the side of the system unit. It
looks like the following:





If the Certificate of Authenticity (COA) sticker is damaged or letters or not legible, you will have to consider the following options:

• Use a digital camera to capture a picture of the COA then enlarge it on your computer.
  

• If the COA sticker is damaged, then you would need to use the recovery partition to reinstall Windows 7, this will exempt the need to use the product key to activate your Windows 7 installation.

• If your recovery partition is not available or damaged, you should
  contact the manufacturer of your computer and request a recovery disc set you can use to reinstall Windows 7. They might charge a small shipping and handling fee. This will exempt the need to use the product key also.

• If none of the above options work or is not available, then its best you purchase a new Windows 10 license:
