Receive only alarms, that is, it eliminates the rest and will only send you those of this type.
Or to those of the applications that you choose from all those that you have installed on your PC that allow this functionality (it is possible to add as many as you want). Also to the Contacts of the mail, Skype or any other program that are anchored in the taskbar. And it gives three alternatives: in reminders, text messages and calls (including VoIP) you can give priority to incoming calls or show notifications regardless of the application they come from. From this option there is a link to Customize the priority list. The other notifications would only reach the activity center.
If you click on the senders, you will see that you can choose if you want that notification to reach you only in the activity center or if you prefer to see it as a small banner on the screen itself (bottom right) or directly on both sites. Some are external (for example, Dropbox, Google Chrome …) and others are internal, that is, from Windows itself ( Security and maintenance, Configuration …). In the same notification setting screen of the Notifications and Actions section, you will see another option entitled Get notifications from these senders, and just below it you will see all the applications and functions that send notifications. Among them, for example, if you want to link the messages with a sound, which are displayed on the lock screen or receive tips and tricks from Windows itself. With the Notifications button activated in blue, you will see that just below it gives you some interesting options that customize this function. Of course, then you can change according to your preferences which notifications you need me to send you and which not. If you want to completely deactivate these messages that warn you of everything that happens on the PC, simply move it to deactivate them (you will see that the blue color disappears). Once inside, you will see a sliding button that says Notifications. In the same window, at the bottom, the icons appear to quickly access some functions (Settings, airplane mode, tablet mode …).
In the Windows 10 activity center you will see all the notifications together, at the top, and from there you can manage them (by clicking on the Manage notifications link).
You also enter this window with the Windows key plus the A key. Another option to open the action center: press the icon located just to the right of the PC clock, in the lower right corner of the screen. Once here, from a link on the right, you can open the activity center.
