Delete an AppLocker Rule

Applies To: Windows 7, Windows Server 2008 R2

This topic describes the steps to delete an AppLocker rule, which will prevent the application that is specified in the rule from running.

As older applications are retired and new applications are deployed in your organization, it will be necessary to modify the application control policies. If an application becomes unsupported by the IT department or is no longer allowed due to the organization's security policy, then deleting the rule or rules associated with that application will prevent the application from running.

For information about testing an AppLocker policy to see what rules affect which files or applications, see Test an AppLocker Policy by Using Test-AppLockerPolicy.

You can perform this task by using Group Policy for an AppLocker policy in a Group Policy Object (GPO) or by using the Local Security Policy snap-in for an AppLocker policy on a local computer.
