What are the steps I'm to take to move my Windows 10 license from HD to SSD?

You can use installation media (a USB flash drive or DVD) to install a new copy of Windows, perform a clean installation, or reinstall Windows 10.

To create the installation media, here's what you'll need:

A PC with a reliable internet connection. The download time will vary, depending on your internet connection.

A USB flash drive or DVD. A blank USB flash drive with at least 8 GB of space, or a blank DVD (and DVD burner). We recommend using a blank USB or blank DVD because any content on it will be deleted. When burning a DVD from an ISO file, if you're told the disc image file is too large, you'll need to use dual layer (DL) DVD media.

Then boot (you may need to change the boot drive starter depending your BIOS. Normally you need to press an F key - F8 sometimes to select the flash drive.) with the USB flash drive and perform a clean installation.
