You will have a legal license by clean installing W10 because the W10 OEM product key is in your notebook's BIOS.
You don't even have to know what the key is, and W10 will automatically find it and activate.
You will have a plain installation of W10 without any of the HP drivers and software that originally came with your notebook, which is why you have to install the drivers and software from the support page.
I also checked your notebook's product number on the cloud recovery tool link and it reported 'Not available.'
I find that odd because the info link to the cloud recovery tool is on your notebook's support page.
I have a HP Stream 11 Pro G4 notebook that has the same issue...link to cloud recovery tool is on the support page but my notebook is not supported.
I have two other HP notebooks with the cloud recovery tool on the support page and they were supported.
