Some of the pinned items in my taskbar show "(2)" when I hold right click down or hoover my cursor over the pinned item. How do I fix this (delete the "(2)")?
You might see if you may get lucky and unpinning and repinning them may help.
If not, then you could use the tutorial below to reset and clear all pinned items on the taskbar. That should fix it for you, but you'll need to manually repin them all again.
