函数原型：
//By MoreWindows-(http://blog.csdn.net/MoreWindows)
BOOLWINAPISetComputerName(
__in LPCTSTRlpComputerName
);
对于计算机名称有一定的要求，MSDN的解释如下：
The computer name that will take effect the next time the computer is started. The name must not be longer than MAX_COMPUTERNAME_LENGTH characters.
The standard character set includes letters, numbers, and the following symbols: ! @ # $ % ^ & ' ) ( . - _ { } ~ . If this parameter contains one or more characters that are outside the standard character set, SetComputerName returns ERROR_INVALID_PARAMETER.

}先修改下
重启后可以发现计算机的名称已经被修改了。
