Recently I opened my Control Panel and saw that a blank icon came up before my list of icons. Has anyone else experienced this before? Is it safe to delete it?

When I try creating a shortcut on the desktop, I get a dialog box saying:
Windows could not create the shortcut. Check if the disk is full.
Clearly the disk isn't full, since I still have 102GB of free hard disk space.
EDIT: *I did a manual search for .CPL in Windows Search and then looked at the list in TweakUI and got 3 unmatched .CPL files. They are ncpa.CPL, sapi.CPL, and QuickTime.CPL. I clearly know the QuickTime one, but not too sure about the rest. SCRATCH THAT, I FIGURED IT OUT... BUT IT'S NOT THE BLANK ICON.
