微软手册只提了一个remove，没提增加，原来是这样。

更改

代码如下:

Set WshShell = Wscript.CreateObject("Wscript.Shell")

WshShell.Environment("user").Item("path")="c:\ruby"

移除：

代码如下:

WshShell.Environment("USER").Remove("LAST_LOGIN_DATE")

附记一下这两个：

代码如下:

Set objAD = CreateObject("ADSystemInfo")

Wscript.Echo "Your Computer Name is " & objAD.ComputerName

Wscript.Echo "Your Username is " & objAD.UserName

WScript.Echo("Hello")

WScript.Interactive = false

WScript.Echo("This wont display")

WScript.Interactive = true

WScript.Echo("This will display")
