代码如下：

    def DeleteQuickLaunchOnTaskBar(lnkName):   
        objShell = win32com.client.Dispatch("Shell.Application")   
           
        taskbarPath = os.path.join(os.environ["appdata"], r'Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar')   
        lnkName = DesktopCommon.ToUnicode(lnkName)   
        objFolder = objShell.NameSpace(taskbarPath)   
        desktopItems = objFolder.Items()   
           
        for item in desktopItems:   
            if DesktopCommon.ToUnicode(item.Name) == lnkName:   
                verbs = item.Verbs()   
                for verb in verbs:   
                    if DesktopCommon.ToUnicode(verb.Name) == u"从任务栏脱离(&K)" or  DesktopCommon.ToUnicode(verb.Name) == u"Unpin from Tas&kbar":   
                        verb.DoIt()
