This article describes how to use a script to change permissions defined in a registry key from a command prompt by using the Regini.exe utility included with Microsoft Windows NT Server 4.0 Resource Kit. The Resource Kit is a separate product that can be purchased from Microsoft.
CAUTION: When you use a script to change registry permissions, you replace the entire set of current permissions defined in a registry key. For example, if you have four types of users whose permissions are defined in a particular registry key, and you create and run a script file that changes the permissions for only three of the four types of users, the information about the fourth type is deleted.
To use a script to change permissions defined in a registry key from a command prompt:
- Install the latest version of the Windows NT Server 4.0 Resource Kit.
- Create a script file that contains the change commands:
- Start any text editor (such as Notepad).
- Type the registry keys and the appropriate permissions in the following format\Registry\hive\key [permissions]where hive is the name of the registry hive, key is the name of the registry key, and [permissions] is the binary number format of the permissions.
For example, to modify the HKEY_LOCAL_MACHINE\Software registry key to give the Administrators group and the Creator/Owner group Full Control permission and the Everyone group Read permission, type the following string:\Registry\Machine\Software [1 5 8]NOTE: You must type the permissions in the binary number format. You must also refer to the registry hive in the predefined format. For more information about how to refer to a registry hive in a script file and about the binary numbers for various types of permissions, refer to the 'Reference to Registry Hives and Binary Number Representation for Permissions' section in this article.
- Save and then close the script file.
- Type the following command at a command prompt, and then press ENTERREGINI [-m \\computername] scriptnamewhere computername is the name of the computer and scriptname is the name of the script file you just created.
NOTE: Use the -m option only when you edit the registry of a remote computer. Be sure to include the entire path to the script file.
Refer to registry hives as indicated below:
HKEY_LOCAL_MACHINE - \Registry\Machine HKEY_USERS - \Registry\Users HKEY_CURRENT_USER - \Registry\User\User_SID (where User_SID is the current user's security identifier)Permissions and their binary number representations are as follows:
Administrator Full 1Administrator R 2Administrator RW 3Administrator RWD 4Creator Full 5Creator RW 6World Full 7World R 8World RW 9World RWD 10Power Users Full 11Power Users RW 12Power Users RWD 13System Op Full 14System Op RW 15System Op RWD 16System Full 17System RW 18System R 19Administrator RWX 20You can use the Regdmp utility, also included with the Resource Kit, to obtain the current permissions of a registry key in the binary number format.
