Creating a Subkey

Microsoft® Windows® 2000 Scripting Guide

« Previous | Next »   

You rarely need to create a registry subkey. However, in some circumstances the solution to a problem as described in a Knowledge Base article or a security bulletin requires the addition of a subkey. If you need to create a subkey on a large number of computers, the best solution might very well be a script. After all, a single script can be used to create the subkey on every computer affected by the problem.

The Registry Provider s CreateKey method enables you to add a new subkey. It takes two parameters: a constant indicating the subtree to which the new subkey will be added and the path of the new subkey.

Scripting Steps

Listing 16.8 contains a script that creates a subkey in the SOFTWARE key under the subtree HKEY_LOCAL_MACHINE in the registry. To carry out this task, the script must perform the following steps:

1. Create a constant to hold the hexadecimal number corresponding to the HKEY_LOCAL_MACHINE registry subtree.
2. Create a variable and set it to computer name.
3. Use a GetObject call to connect to the WMI namespace root\default, and set the impersonation level to "impersonate."
4. Create a variable and set it to the path of the registry subkey to create.
5. Use the CreateKey method to create the new subkey.
