HP Laptop CD Key



Some models came with W10 and the product key is in the BIOS.


Some models came with FreeDOS and the user supplies their own operating system.


The only suggestion I can offer would be to use the Microsoft media creation tool to create a bootable installation USB drive, and install W10.  I would try W10 Pro first, since it is a business-class notebook.


If the PC came with W10, then the installation media should work, install W10, and automatically activate.


If it does not activate, use the free utility that I zipped up and attached below, that will show you what version of W10 the product key is good for, and you can install that version instead.
