Why is my Action Center tray icon missing?

There was action center icon in another user ,in my computer but not in mine,thanks.

But same system files are there,how come that user has action center ,and not mine

My Action Center tray icon is missing for a while and even after I right click and click properties on the tray, I can't turn it back on since it's grayed out. I tried methods of editing the registry, but no luck.

i too suffered with the same problem you just need to open registry editor and create a registry name EnableNotificationCenter in hkey current user>software>microsoft>windows>explorer and set its value to 1.. check this out for more help https://www.youtube.com/watch?v=KAVOFbejbOo
