The product key is in the BIOS.  Microsoft quit using product key stickers after W7.


If your notebook came with W8.1 from HP, and not W8.1 with Bing, you can reinstall W8.1 by downloading the ISO file from the link below.  Choose the applicable file download for the version of W8.1 your notebook came with.


If you downloaded the correct version of W8.1, it won't ask for a product key, and it will install and automatically activate once you are connected to the internet.


Use the Microsoft utility that I zipped up and attached below to transfer the ISO file to a DVD or USB flash drive so that it is bootable.
