Windows 10: Windows 10 transfer to a new SSD

I have a old HDD that has windows 10 and I have got a whole new pc but that is the only piece I brought over from my old set up to keep windows 10, I purchased a SSD and heard that I have if I have my windows 10 connected to my Microsoft account there was a way to transfer the windows 10 instead of buying it again. I also heard I can "clone" it over but I would rather do it the legit way and not have something mess up doing that. So what do I do to have windows 10 on my new SSD?

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
