Hi,

If Windows 10 was already installed on the notebook, you do not need product key. If you reinstall the same version (Home), once installed and connected to internet Windows will automatically activate.

 

Hope it helps,

David

@Shakar 

If you installed a DIFFERENT version of Windows than what came with the PC, then as @iomare pointed out, the new version will not activate.  Since HP does not provide extra OEM keys, you would then have to BUY a key to match the version you installed -- either Home or Pro.
