推荐答案

根据其他的答案，似乎这是可以做到的。虽然我非常不鼓励这样。就拿你的程序应该因为某些原因挂（上帝保佑...）。然后，你将有这种情况，唯一的用户可以做的是关闭计算机的电源按钮（或拔出插头...）。

Based on other answers, it seems that this is possible to do. Although I highly discourage this. Take for instance that your program should for some reason hang (god forbid...). Then you would have the situation that the only thing the user can do is to turn off the computer with the power button (or pull the plug...).

这是一个很好的理由，这是很难做到的，而方法是不良记录...

It is for a good reason that this is difficult to do, and the methods are poorly documented...

这看起来像是要走的路的唯一途径，是的皮埃尔 - 阿兰·Vigeant 的评论如果这是一个小亭电脑什么的。然后，它实际上是有意义的做到这一点！

The only way this looks like the way to go, is the comment from Pierre-Alain Vigeant if this is a kiosk computer or something. Then it would actually make sense to do this!
