Can't pin items onto the taskbar because of a program on the taskbar

[Minecrafter]

Hello. Let me explain my problem.

I had a program installed called Spiral Knights, and I pinned the icon onto the taskbar so I could quickly launch it. When I was done playing it for good, I uninstalled it and it looked like the icon was off the taskbar, but it wasn't. When I tried to put another program onto the taskbar, called minecraft_server.jar, it pinned to the Spiral Knights icon, even though SK isn't installed anymore. Wherever I try to put the minecraft_server.jar onto the taskbar, the SK program is still there, and it says if I want to pin the minecraft_server.jar onto SK. Please help!

looks like your task bar is unlocked. could you right click on your task bar, click on tool bars and see if there is any thing named "Spiral Knights"?

 

[Minecrafter]

No, there isn't.

 

[koolkat77]

have you tried dragging these bars? and seeing if any folder appears?

 

[Minecrafter]

Yeah, doesn`t work.

.jar is a file as far as Windows is concerned. Only .exe (Executable) can be pinned.
Files get pinned to shortcut's jump list.
