1、新建一个记事本。
2、将下面代码内容复制到记事本中，另存为.reg文件。
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Control/SafeBoot/Network/{4D36E96C-E325-11CE-BFC1-08002BE10318}]
@=”[6cFgE][Şοûпđ, νìδ℮ô άήδ ğªмè ¢őήťřόℓŀèґš !!! !!! !]”
[HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Control/SafeBoot/Network/{640167b4-59b0-47a6-b335-a6b3c0695aea}]
