Windows 10: Taskbar Icons

I've got a Taskbar Icons, like; when I move my mouse to any Icon, the highlight thing that when I move it to an icon stays and never go, and I have to reboot/restart my PC if I have to fix it. It's really annoying me, and it's not the first time.
I want to ask why is this happening and I don't see any problem..

:)

 

Icons in taskbar disappeared; pinning same icon in taskbar now shows "icon (2)"

ok, maybe I'm not describing my problem correctly.

As far as I know, I have only one taskbar active.

I right click on an app & select 'pin to taskbar', it appears in the taskbar as 'Icon'.

I right click on the same app & select 'pin to taskbar', it appears in the taskbar as 'Icon(2)'.

Now I have two icons of the same app (Icon & Icon(2)).

In my situation, the first 'Icon' disappeared somehow & only 'Icon(2)' is visible.

I then unpin 'Icon(2)' from the taskbar.

I then right click on the same app & select 'pin to taskbar', BUT instead on 'Icon' appearing in the taskbar, 'Icon(2)' appears! This leads me to believe that 'Icon' is still pinned to the taskbar BUT not VISIBLE.

The question is how do I correct this?

 

Pin to taskbar

Just drag that icon from desktop to taskbar. It will pin it to taskbar by creating an icon on taskbar.

 

A few people have reported this behaviour. It has happened before in Win 7 and 8.

The following might work:

Open Task Manager (right click on taskbar) and click on More Details. Find and restart Windows Explorer in the process tab.

This will save you having to reboot the PC but I'm afraid it is not a permanent fix and I do not know of one.
