Issue: How to Fix Action Center if It Won’t Open?

I used to receive a pop-up „New Notifications“ on the Action Center, but when I open it, there are no new notifications. Unfortunately, but for the past couple of days, I can‘t access the Action Center at all. It seems that the other icons in the system tray are also inactive. What should I do?

Solved Answer

Action Center is a Windows feature that was first introduced by Windows XP operating system. It keeps PC users informed about the condition of the system and the urgent tasks that he/she has to perform. When the Action Center has an alert, for example, about an available installation of a Creators Update, the Action Center displays a small pop-up box saying „New Notifications.“ The icon of Action Center looks like a small text box. Since it is not always placed on the taskbar, you should certainly notice the „newcomer.“ To check for the new notifications, the PC owner has to click on the Action Center icon. On the one hand, this feature is useful as it keeps the user informed about the current state of the system. On the other hand, Action Center pop-ups may become annoying. Many people reported that pop-ups like „Windows Defender needs to scan your PC“  remains on the taskbar even if the user opens the Action Center and checks it. Besides, Action Center may display perverse notifications, which report about „New Notifications“ while in reality, there are no new notifications all. Recently, several people reported the service for being unavailable. The Action Center icon is grayed out and does not respond. Luckily, here is a couple of things that you can do to fix Action Center errors on Windows quite easily.
