Reset offers two types of clean installs:
Just remove my files - this option is quicker and recommended if you just want a fresh start and you plan to keep the computer.
Remove files and clean the drive - if you plan to giveaway or resell your computer, this option ensures the computer is cleaned properly. Its takes a bit longer, but it is recommended if you plan to no longer use this computer.

Option 3:
When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft Activation Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.
Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate. You will prompted to enter a product key a couple times through the installation, click I don't have a key and Do this later.
There is no need to know or get a new key, but if you have issues with Digital Licensing or the Activation Troubleshooter, you can utilize an existing Windows 7 or Windows 8/8.1 product key you already own to reactivate if necessary. or use the reset function in Windows 10.
Go to a working computer, download, create a bootable copy, then perform a clean install.
