HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0000、0001、0002等主键下，查找DriverDesc的内容，了解网卡使用了哪个主键（例如0001），如果主键下有params项，则该主键也是网卡所使用的；

　　例如网卡使用了0001主键，因此我们就选中它，在其右边建一个字符串项（名为NetworkAddress），双击该串，输入你指定的MAC地址值（注意应该是12位的连续数字或字母，其间没有-号）；在0001下的NDI\params中添加一项子键（名为NetworkAddress），选择该子键，在其右边添加名为default的字符串，键值为修改后的MAC地址，与上面的数值相同；修改后重启生效。

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0001 NetworkAddress的键值 修改老乱码

ok 搞定了。现在没有乱码。

可以结贴了吧。别忘了给分。

'改成这样试试

键值变成乱码了不知道什么原因

[caofusheng]

那个键值？
