About Group Policy Settings
Describes the Group Policy settings for Windows PowerShell
Windows PowerShell includes Group Policy settings to help you define consistent option values for servers in an enterprise environment.
The Windows PowerShell Group Policy settings are in the following Group Policy paths:
Computer Configuration\Administrative Templates\Windows Components\Windows PowerShell User Configuration\Administrative Templates\Windows Components\Windows PowerShell
Group policy settings in the User Configuration path take precedence over Group Policy settings in the Computer Configuration path.
The policies are as follows:
Turn on Script Execution: Sets the Windows PowerShell execution policy. Turn on Module Logging: Sets the LogPipelineExecutionDetails property of modules. Set the default source path for Update-Help: Sets the source for UpdatableHelp to a directory, not the Internet.
To download spreadsheets that list all of the Group Policy settings for each version of Windows, see "Group Policy Settings Reference for Windows and Windows Server" in the Microsoft Download Center at http://go.microsoft.com/fwlink/?LinkId=261775
TURN ON SCRIPT EXECUTION
The "Turn on Script Execution" policy setting sets the execution policy for computers and users, which determines which scripts are permitted to run.
If you enable the policy setting, you can select from among the following policy settings.
-- "Allow only signed scripts" allows scripts to execute only if they are signed by a trusted publisher. This policy setting is equivalent to the AllSigned execution policy.
-- "Allow local scripts and remote signed scripts" allows all local scripts to run. Scripts that originate from the Internet must be signed by a trusted publisher. This policy setting is equivalent to the RemoteSigned execution policy.
-- "Allow all scripts" allows all scripts to run. This policy setting is equivalent to the Unrestricted execution policy.
If you disable this policy setting, no scripts are allowed to run. This policy setting is equivalent to the Restricted execution policy.
If you disable or do not configure this policy setting, the execution policy that is set for the computer or user by the Set-ExecutionPolicy cmdlet determines whether scripts are permitted to run. The default value is Restricted.
For more information, see about_Execution_Policies (http://go.microsoft.com/fwlink/?LinkID=135170).
TURN ON MODULE LOGGING
The "Turn on Module Logging" policy setting turns on logging for selected Windows PowerShell modules. The setting is effective in all sessions on all affected computers.
If you enable this policy setting and specify one or more modules, pipeline execution events for the specified modules are recorded in the Windows PowerShell log in Event Viewer.
If you disable this policy setting, logging of execution events is disabled for all Windows PowerShell modules.
If this policy setting is not configured, the LogPipelineExecutionDetails property of each module or snap-in determines whether the execution events of a module or snap-in are logged. By default, the LogPipelineExecutionDetails property of all modules and snap-ins is set to False.
To turn on module logging for a module, use the following command format. The module must be imported into the session and the setting is effective only in the current session.PS C:> Import-Module
To turn on module logging for all sessions on a particular computer, add the previous commands to the all-users Windows PowerShell profile ($Profile.AllUsers.AllHosts).

SET THE DEFAULT SOURCE PATH FOR UPDATE-HELP
The "Set the Default Source Path for Update-Help" policy setting sets a default value for the SourcePath parameter of the Update-Help cmdlet. This setting prevents users from using the Update-Help cmdlet to download help files from the Internet.
NOTE: The "Set the default source path for Update-Help" Group Policy setting appears under Computer Configuration and User Configuration. However, only the Group Policy setting under Computer Configuration is effective. The Group Policy setting under User Configuration is ignored.
The Update-Help cmdlet downloads and installs the newest help files for Windows PowerShell modules and installs them on the computer. By default, Update-Help downloads new help files from an Internet location specified by the module.
However, you can use the Save-Help cmdlet to download the newest help files to a file system location, such as a network share, and then use the Update-Help cmdlet to get the help files from the file system location and install them on the computer. The SourcePath parameter of the Update-Help cmdlet specifies the file system location.
By providing a default value for the SourcePath parameter, this Group Policy setting implicitly adds the SourcePath parameter to all Update-Help commands. Users can override the particular file system location specified as the default value by entering a different file system location. But they cannot remove the SourcePath parameter from the Update-Help command.
If you enable this policy setting, you can specify a default value for the SourcePath parameter. Enter a file system location.
If this policy setting is disabled or not configured, there is no default value for the SourcePath parameter of the Update-Help cmdlet. Users can download help from the Internet or from any file system location.
