为什么我调用的WIN API不能实现关机功能？

[MilkyStone]

按win API参考资料，ExitwindowsEx可以实现关机，但我执行VI，只能实现注销系统的功能，为什么呢？

资料上说，uflag=0注销，uflag=1关机，uflag=2重启，uflag=4关闭电源，但我执行时当uflag=0，4时功能都是一样的，只注销系统，而当uflag=1，2时没有任何反应。

那位高手可以指教？

谢谢！

Specifically read to alinea about AdjustTokenPrivileges on MSDN ExitWindowsEx.

This kind of stuff gets ugly very fast to be implemented with Call Library Nodes only and I would advise writing a DLL instead.
That said I believe there is such a solution already here on the Developer Exchange, so searching a little might be a good idea.
