Take Control of Problems with Action Center
In Windows 7, you’ll see fewer notifications popping up because Action Center consolidates alerts from 10 Windows features, including Security Center and Windows Defender. When Windows 7 needs your attention, you’ll see a new icon in the notification area and can find out more by clicking it. You can choose to respond to the notification or go to Action Center for more details. If you don’t have time to address the issue immediately, Action Center will keep the information waiting for you to address later.
