Windows 10 Action Center is useful as it can display various notifications of different programs as well as quick actions/notification icons.
However, it can get very cluttered when many unimportant notifications start popping up. Also, not all quick actions are needed for regular use. So these can be rearranged/added or removed.
Here is how :
Right click on date/time from system tray and choose Customize notification icons.
From the Quick actions layout, drag and drop icons to rearrange them.
To remove certain quick actions, click on Add or remove quick actions. Enable and disable as needed.
To change general notification settings, select as needed from Notifications .
For program specific notifications, turn them on/off from Get notifications from these senders section.
This can streamline how and when notifications are displayed in Action Center.
