Here's how it works. When Windows Defender detects software or changes by software not yet classified for risks, you see how other members responded to the alert. In turn, the actions that you apply are shared with the community to help other members decide how to respond. If you join, Windows Defender automatically sends information to help Microsoft decide which software to investigate for potential threats and to improve how Windows Defender works.
