Regarding windows key, got Hard disk replaced.

[Divyansh548]

Actually I got the hard disk replaced of my hp pavilion laptop, but now I don't have my original Windows 10 key.

So I just wanted your help as to where I will be able to find my original windows key.

You can't -- as HP keeps no records of individual product keys associated with individual PCs.

If you are worried about reinstalling Windows, you should use the HP Cloud Recovery option as it will find and reuse your key:

If your PC is a 2016 model or newer, you should see if you can make a bootable USB recovery drive using the HP cloud recovery tool on a working PC.

The recovery drive can then be used to install Win10 and the HP drivers and utilities that originally came with your PC.

Hi, @Divyansh548 

Your notebook's model series is not supported by the HP cloud recovery tool.

The W10 product key is in the BIOS.

Here is how you can reinstall W10 for free...

Make bootable installation media using the Media creation tool on another Windows PC running W7 or newer on it.

Make the 64 bit installation media.

The installer will automatically pick up the product key and the version of W10 that came with the PC.

After W10 has completed installing, you can install the drivers and available software from your notebook's support page.
