Or you can click Clear All in the upper right corner of the notifications center to dismiss all notifications from all apps. You can also mouse over each individual notification and click the X next to it to dismiss that specific notification. You can dismiss notifications three different ways: You can mouse over the app name (Twitter) and click the X next to it to dismiss all notifications from that app. Screenshot by Sarah Jacobsson Purewal/CNET Mouse over notifications and click the 'X' to dismiss them.

In the notifications area you'll see notifications from various apps, including Windows system apps and third-party apps like Twitter, Facebook and your email account. The new action center consists of two parts: the notifications area at the top and the 'quick actions' bar at the bottom.
