用TerminateProcess把一个进程结束后有个问题，就是如果该程序在托盘有图标的话，这个图标并不会在它被结束时也消失。当然你用鼠标从上面移过可以解决这个问题，但本人在用自己的刷新辅助软件“疯狂刷新”的时候，每5分钟结束一次，一天下来如果不动电脑，就会在托盘区生成NNN个死图标，即使你拚命去点，也要点半天才能全部消除。有没有办法一下子搞定它呢？答案是肯定的，在网上搜了很久……用Delphi编写几行代码搞定。

添加自定义类型，用作判断系统类型，
type
    TOSVersion = (osUnknown, os95, os98, osME, osNT3, osNT4, os2K, osXP, os2K3);

添加自定义函数过程

function GetOS: TOSVersion; //获得系统类型，用来取得托盘句柄
var
    OS: TOSVersionInfo;
begin
    ZeroMemory(@OS, SizeOf(OS));
    OS.dwOSVersionInfoSize := SizeOf(OS);
    GetVersionEx(OS);
    Result := osUnknown;
    if OS.dwPlatformId = VER_PLATFORM_WIN32_NT then begin
        case OS.dwMajorVersion of
            3: Result := osNT3;
            4: Result := osNT4;
            5: begin
                    case OS.dwMinorVersion of
                        0: Result := os2K;
                        1: Result := osXP;
                        2: Result := os2K3;
                    end;
                end;
        end;
    end
    else if (OS.dwMajorVersion = 4) and (OS.dwMinorVersion = 0) then
        Result := os95
    else if (OS.dwMajorVersion = 4) and (OS.dwMinorVersion = 10) then
        Result := os98
    else if (OS.dwMajorVersion = 4) and (OS.dwMinorVersion = 90) then
        Result := osME
end;

function GetSysTrayWnd(): HWND; //返回系统托盘的句柄，适合于Windows各版本
var OS: TOSVersion;
begin
    OS := GetOS;
    Result := FindWindow('Shell_TrayWnd', nil);
    Result := FindWindowEx(Result, 0, 'TrayNotifyWnd', nil);
    if (OS in [osXP, os2K3]) then
        Result := FindWindowEx(Result, 0, 'SysPager', nil);
    if (OS in [os2K, osXP, os2K3]) then
        Result := FindWindowEx(Result, 0, 'ToolbarWindow32', nil);
end;

procedure KillTrayIcons (Sender: TObject);
var
    hwndTrayToolBar: HWND;
    rTrayToolBar: tRect;
    x, y: Word;
begin
    hwndTrayToolBar := GetSysTrayWnd;
    Windows.GetClientRect(hwndTrayToolBar, rTrayToolBar);
    for x := 1 to rTrayToolBar.right - 1 do begin
        for y := 1 to rTrayToolBar.bottom - 1 do begin
            SendMessage(hwndTrayToolBar, WM_MOUSEMOVE, 0, MAKELPARAM(x, y));
        end;
    end;
end;

//调用 KillTrayIcons(self) 过程就可以瞬间清除所有无用的托盘图标了。

经过本人测试，Delphi7+XP系统下确实可以用。
