//Get tray window handle and bounding rectangle
TrayWindow := FindWindowEx(FindWindow('Shell_TrayWnd',NIL),0,'TrayNotifyWnd',NIL);
if not GetWindowRect(TrayWindow,WindowRect) then
Exit;
// Get small icon metrics
SmallIconWidth := GetSystemMetrics(SM_CXSMICON);
SmallIconHeight := GetSystemMetrics(SM_CYSMICON);
// Save current mouse position
GetCursorPos(CursorPos);
// Sweep the mouse cursor over each icon in the tray in both dimensions
with WindowRect do
begin
for Row := 0 to (Bottom - Top) DIV SmallIconHeight do

for Col := 0 to (Right - Left) DIV SmallIconWidth do
begin
SetCursorPos(Left + Col * SmallIconWidth, Top + Row * SmallIconHeight);
Sleep(0);
end;
end;
end;
//Restore mouse position

//Redraw tray window (to fix bug in multi-line tray area)
RedrawWindow(TrayWindow,NIL,0,RDW_INVALIDATE OR RDW_ERASE OR RDW_UPDATENOW);
