Clean up custom Notification (Show Hidden Icons)

Clean up custom Notification (Show Hidden Icons):

HKCU\Software\Microsoft\Windows\Current Version\Explorer\TrayNotify
Delete keys: IconStreams and PastIconStream (Binary)
Note: This is an extreme step that will completely clear the Notification Area. Also, restart Explorer to clear the current list. Ctrl+Alt+Del > task Manager > Processes > select explorer.exe > End Process (DO NOT CLOSE TASK MANAGER!) > File > New task > type Explorer >OK.
