I just want to get my windows 8 update to windows 8.1, but I don't know how to do it? Do I need a serial number?

Make sure you are up to date for your windows updates and then go to the Microsoft store on your computer. There will be a large advertisement for the 8.1 update.

You'll need update installer of Windows 8.1 from Microsoft Store. Yes, License will be required. You'll have to purchase it unless Microsoft offers some promotion

You already own Windows 8 so there is no fee to upgrade.
