WMI StdRegProv 通过wmi操作注册表的vbscript实现代码 (本地或远程)，需要的朋友可以参考下。

Because of its length, only the code for the function itself is shown on this page.
The demo script that shows how to use this function is available as a separate download.

Function ReadRegValue( myComputer, myRegPath, myRegValue )
' This function reads a value from the registry of any WMI
' enabled computer.
'
' Arguments:
' myComputer a computer name or IP address,
' or a dot for the local computer
' myRegPath a full registry key path, e.g.
' HKEY_CLASSES_ROOT\.jpg or
' HKLM\SOFTWARE\Microsoft\DirectX
' myRegValue the value name to be queried, e.g.
' InstalledVersion or "" for default
' values
'
' The function returns an array with the following elements:
' ReadRegValue(0) the computer name (the first argument)
' ReadRegValue(1) the hive number (see const declarations)
' ReadRegValue(2) the key path without the hive
' ReadRegValue(3) the value name (the third argument)
' ReadRegValue(4) the error number: 0 means no error
' ReadRegValue(5) the data type of the result
' ReadRegValue(6) the actual data, or the first element of an
' array of data for REG_BINARY or REG_MULTI_SZ
