故障现象：程序在运行，但是任务栏却不显示相应的按钮，导致多个程序同时运行时，无法从任务栏迅速切换，只能用 Alt+TAB 键切换，既慢又不直观，还经常错误切换到其他程序。
解决过程：一直不太敢用网上所谓修改、强化任务栏的软件，怕有垃圾代码/病毒/后门/木马/恶意代码等留在系统中（这个故障很可能就是安装某个软件引起的），导致旧病不除又添新病（即使除了旧病，也是得不偿失）。今天终于发现一个方法貌似解决这个问题的。而且妙的是它不是一个软件，而是一段VB Script代码，自己可以查看，有知情权。
代码：

仔细看了看，基本上都是注册表的操作，应该没有恶意代码, 复制粘贴后保存后缀名为.vbs的文件,双击运行,任务栏会回到初始状态,右击选择"快速启动栏","语言栏","Windows Media Player",久违的任务栏终于回来了!!!
