Problem with"Select Which Icons Appear On Taskbar"

[TheGhost]

This question has been asked before, "I have a question, under "Start Menu -> Settings -> Notifications & actions -> Select icons which appear on the taskbar", how does one do maintenance on the list so it only shows items that are currently installed as it seems uninstalled items are still showing up on the list." However the answer has been tried but did not solve it for me. I still have uninstalled app icons showing up. I have deleted "iconstreams", there is no "pasticonstreams" to delete, I have ran registry cleaner, disk clean up, registry search for the apps, c:\ drive search for left overs etc etc etc to no avail. The icons or app shortcuts must be hiding somewhere but the question is where? Any help would be appreciated. The Ghost......
