My icon for "Show Hidden Icons" in the Taskbar, as well as other system-related icons, has gone missing, replaced by an empty box. Applications on the Taskbar are OK, but the MS System icons have been replaced by a tall empty box. They still work, but do not appear as they should. The desktop icons, including Recycle Bin, and application icons are OK. This is just for icons that show in the right side of the Taskbar as well as many in System Apps/Settings and perhaps elsewhere. Any idea of how to fix this without drastic measures?

Remove Linux Desktop Icons

I am not sure whether this will work (Ubuntu does not have icons like that on the desktop by default), but I suggest opening the trash bin and sweeping the icons into the window showing the trash bin.

Some icons missing in W7

Why are some of my icons missing? Not just the shortcuts of those pinned in the start menu, the programs themselves lost their icons. Yet other times they re-appear.
