Windows 10: Windows 10 problem with duplicated icons in taskbar, broken Jump Lists

Hello,


I‘ve been recently having a problem with duplicated items in taskbar and broken Jump Lists. I‘m now using Windows 10 but this problem occurred in Windows 8.1 too but then it somehow fixed itself. Some programs that I pin to taskbar have a tendency to duplicate themselves when clicked on. For now, I‘ve noticed this behaviour only in Skype and Spotify but it‘s still very annoying since duplicate icons take valuable taskbar space and even more—make Jump Lists of those programs broken, meaning that you can still see tasks program developers provided but after you click them nothing happens.


I‘ve tried loads of times pinning, repinning, deleting whole User Pinned folder from %appdata%/Microsoft/Internet Explorer/Quick Launch, clearing Jump List folders manually and automatically with Command Prompt commands as suggested here with no luck. The only thing I did achieve was when I pinned Skype to taskbar in my other user account, then copied the newly created shortcut from Use Pinned folder to my User Pinned folder—this made Skype Jump Lists working but duplicate icon in taskbar remained.


I‘ve recently found a tutorial which may force taskbar to use only one icon per app but I can‘t check this right now as 7+ Taskbar Tweaker isn‘t yet officially available for Windows 10 users.


Thank you for taking your time and reading my message, any suggestions would be appreciated,





P. S. I don‘t know if this is related but I can‘t pin any Control Panel item to Quick Access whilst I can pin folders. Interesting side of this is that pinned Control Panel items appear in File Explorer's Jump List but after clicked I get a message that item is unavailable and that it might have been moved, renamed or removed.

Windows 10 Start Menu issues after mysterious update.

FWIW I rarely use the Windows 10 Start Menu. Most of the time I access using icons with Jump Lists on the Taskbar and, if that is not suitable, I right click the Start icon on the Taskbar.

 

Windows 10 Jump List on taskbar when click on to run does not open any programs or history/recent/frequent files

If I may add to this:

I run four systems, all upgraded to Windows 10.

On three - if I move the mouse over a pinned taskbar icon and right click, the jump list pops up and stays up until something is clicked.

On one, when I move the mouse over an icon and right click, the jump list pops up but as soon as the cursor is moved it drops down. The jump list works fine if Alt or Ctrl is pressed.

Anyone know where in the inner framework of Windows 10 the code that controls the taskbar jump items might be?

 

I'm new to windows 10 and experiencing duplicate task bar items but ONLY for firefox. My work computer also has a recent upgrade to W10 and it is NOT having this problem. It's annoying. I've tried unpinning and repinning from the start screen shortcut and from the actual executable file itself. I've also tried unpinning the original and pinning one of the duplicates.

Nothing is working to fix this bug.
