I cleaned up my Taskbar by following a guide and yet not following the "export/backup registry entries before removing/deleting them" part of the guide. Taskbar pinning became impossible because I deleted all registry entries in: Entries there were not only specific to the items pinned to my taskbar, but also tied something else, like username. I found my PC hostname in one of those entries before deleting them. Without re-generating those entries, there was no way to add items to my taskbar. Shortcuts no longer appear when placed in: I tried exporting those keys from another user on another PC and it worked, but only for shortcuts of that other user from another PC. My shortcuts didn't show up. for Any idea how to regenerate those keys? Again, I think they are dependent upon username, PC hostname, but how do I regenerate them to include those dependencies?
