Brian Lich|Last Updated: 3/8/2017

SYNOPSIS

Sets the AppLocker policy for the specified GPO.

SYNTAX

ByXmlPolicy (Default)

Set-AppLockerPolicy [-XmlPolicy] <String> [-Ldap <String>] [-Merge] [-WhatIf] [-Confirm] [<CommonParameters>]

ByPolicyObject

Set-AppLockerPolicy [-PolicyObject] <AppLockerPolicy> [-Ldap <String>] [-Merge] [-WhatIf] [-Confirm]
 [<CommonParameters>]

DESCRIPTION

The Set-AppLockerPolicy cmdlet sets the specified GPO to contain the specified AppLocker policy. If no Lightweight Directory Access Protocol (LDAP) is specified, then the default is the local GPO.

The input values for the AppLocker policy can be an AppLockerPolicy object or an XML-formatted file that contains the AppLocker policy.

EXAMPLES

Example 1: Set the local AppLocker policy

PS C:\> Set-AppLockerPolicy -XMLPolicy C:\Policy.xml

This example sets the local AppLocker policy to the policy specified in C:\Policy.xml.

Example 2: Set the GPO to contain an AppLocker policy.

PS C:\> Set-AppLockerPolicy -XMLPolicy C:\Policy.xml -LDAP "LDAP://DC13.Contoso.com/CN={31B2F340-016D-11D2-945F-00C04FB984F9},CN=Policies,CN=System,DC=Contoso,DC=com"

This example sets the GPO specified in the LDAP path to contain the AppLocker policy that is specified in C:\Policy.xml.

Example 3: Merge the local AppLocker policy with another

PS C:\> Get-AppLockerPolicy -Local | Set-AppLockerPolicy -LDAP "LDAP://DC13.Contoso.com/CN={31B2F340-016D-11D2-945F-00C04FB984F9},CN=Policies,CN=System,DC=Contoso,DC=com" -Merge

This example gets the local AppLocker policy, and then merges the policy with the existing AppLocker policy in the GPO specified in the LDAP path. For more information on how two policies are merged, see the Merge parameter description.
