Windows 10: How to find/backup Windows 10 on a laptop

I've just bought an Asus Win 10 laptop and noticed that there is no CD-key at the bottom and the laptop does not prompt me to make a recovery disc. How do I backup my windows copy if I need to reformat or if the HD becomes corrupt? The last laptop I bought in 2013 had a key.

Does anyone know?

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
