Create Registry Key (and Subkeys)?

Question

I am trying to create a registry key and subkey for enabling IE 11 enterprise mode for all users on a machine. This is what I am using for my VBScript currently and it is failing horribly (does not add the key). I could use some assistance in getting this corrected.

    Const HKEY_LOCAL_MACHINE = &H80000002

    strComputer = "."

    Set ObjRegistry = _
        GetObject("winmgmts:{impersonationLevel = impersonate}! \\" & _
        strComputer & "\root\default:StdRegProv")

    strPath = strKeyPath & "\" & strSubPath
    strKeyPath = "Software\Policies\Microsoft"
    strSubPath = "Internet Explorer\Main\EnterpriseMode"
    strName = "Enabled" 

    ObjRegistry.CreateKey (HKEY_LOCAL_MACHINE, strPath)
    ObjRegistry.SetStringValue HKEY_LOCAL_MACHINE, strPath, strName, strValue
    MsgBox "Successfully enabled Internet Explorer Enterprise Mode." 
End Function

There are several issues with your code, aside from the fact that you posted an incomplete code sample.

• "winmgmts:{impersonationLevel = impersonate}! \\" & strComputer & "\root\default:StdRegProv"
  The WMI moniker contains a spurious space between security settings and path (...! \\...). Remove it.
  As a side note, it's pointless to use a variable for the hostname if that hostname never changes.
• strPath = strKeyPath & "\" & strSubPath
  You define strPath before you define the variables you build the path from. Also, your path components are defined as string literals, so you could drop the concatenation and the additional variables and simply define strPath as a string literal.
• ObjRegistry.CreateKey (HKEY_LOCAL_MACHINE, strPath)
  You must not put argument lists in parentheses unless you're calling the function/method/procedure in a subexpression context. See here for more details. However, you may want to check the return value of your method calls to see if they were successful.

And FTR, hungarian notation is pointless code bloat. Don't use it.

Modified code:

Function SetEnterpriseMode(value)
    Const HKLM = &h80000002

    Set reg = GetObject("winmgmts:{impersonationLevel=impersonate}!//./root/default:StdRegProv")

    path = "Software\Policies\Microsoft\Internet Explorer\Main\EnterpriseMode"
    name = "Enabled"

    rc = reg.CreateKey(HKLM, path)
    If rc <> 0 Then
        MsgBox "Cannot create key (" & rc & ")."
        Exit Function
    End If

    rc = reg.SetStringValue(HKLM, path, name, value)
    If rc = 0 Then
        MsgBox "Successfully enabled Internet Explorer Enterprise Mode."
    Else
        MsgBox "Cannot set value (" & rc & ")."
    End If
End Function
