The Action Center in Windows 10 shows all the notifications from various sources (desktop apps, modern apps, as well as system notifications) and group them together by apps and time. You have all the notifications there and you can see them if you missed them and can later clear them all or just some of them. Also, there are Quick Actions placed at the bottom to quickly toggle some settings (like brightness, Airplane mode, etc) or open certain tools/items like Note, All settings, Connect, etc.
While I like Action Center but many users find it annoying and want to disable it. This can be done with a modification in Window registry file(s). Once it’s disabled, you can’t open it by clicking it’s icon on the taskbar notification area (it’s icon is gone). Also, you’ll receive the notification’s but you’ll not be able to review them later in case you miss them as you could do in Action Center.
Disable Action Center in Windows 10
If you want to disable the Action Center, open the Registry Editor first. You can do that by pressing Win+R key combination to open the Run window and type in Regedit and hit Enter to open the Registry Editor.
Now Namvigate to the following key: HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows\Explorer
Now just restart your PC or Windows Explorer (to do that, open Task Manager and right click on Windows Explorer and click on Restart) and the Action Center will be gone.
Enable Action Center in Windows 10
If you want to enable the Action Center again, you can do that by following the above steps and assigning 0 as the value instead of 1 to the DisableNotificationCenter DWORD (32-bit) Value. The change would take affect after a system reboot or after restarting the Windows Explorer (to do that, open Task Manager and right click on Windows Explorer and click on Restart).
