Invoke-GPUpdate

Schedule a remote Group Policy refresh (gpupdate) on the specified computer.

Syntax

Parameter Set: NonSyncSet
Invoke-GPUpdate [[-Computer] <String> ] [[-RandomDelayInMinutes] <Int32> ] [-AsJob] [-Boot] [-Force] [-LogOff] [-Target <String> ] [ <CommonParameters>]

Parameter Set: SyncSet
Invoke-GPUpdate [[-Computer] <String> ] [[-RandomDelayInMinutes] <Int32> ] [-AsJob] [-Boot] [-LogOff] [-Sync] [-Target <String> ] [ <CommonParameters>]

Detailed Description

The Invoke-GPUpdate cmdlet refreshes Group Policy settings, including security settings that are set on remote computers by scheduling the running of the Gpupdate command on a remote computer. You can combine this cmdlet in a scripted fashion to schedule the Gpupdate command on a group of computers.

The refresh can be scheduled to immediately start a refresh of policy settings or wait for a specified period of time, up to a maximum of 31 days. To avoid putting a load on the network, the refresh times will be offset by a random delay.

Parameters

-AsJob

-Boot

Causes a computer restart after the Group Policy settings are applied. This is required for those Group Policy client side extensions (CSEs) that do not process Group Policy on a background update cycle, but do process Group Policy at computer startup, for example, per-computer Software Installation policy settings.

This parameter has no effect if there are no CSEs called that require a restart.

-Computer<String>

Specifies the name of the computer for which to schedule a Group Policy refresh. You can specify the computer name in one of the following formats:

-- Full computer name (FQDN computer name); for example, computer-01.sales.contoso.com.

-- Fully qualified domain name (FQDN)\computer name; for example, sales.contoso.com\computer-01.

-- NetBIOS domain name\computer name; for example, sales\computer-01.

-- Computer name (host name): for example, computer-01.

If the computer name is not specified the computer, on which the Invoke-GPUpdate cmdlet was run, will have the Group Policy settings refreshed.

-Force

Reapplies all policy settings. By default, Group Policy is only refreshed when policy settings have changed.

-LogOff

Causes a logoff after the policy settings have been updated. This is required for those Group Policy client-side extensions (CSEs) that do not process Group Policy on a background update cycle but do process Group Policy when a user logs on. Examples include per-user Software Installation policy settings and the Folder Redirection extension.

This parameter has no effect if there are no CSEs called that require a logoff.

-RandomDelayInMinutes<Int32>

Specifies the delay, in minutes that Task Scheduler will wait, with a random factor added to lower the network load, before running a scheduled Group Policy refresh.

You can specify a delay in from 0 minutes to a maximum of 44640 minutes (31 days):

-- A value of 0 will cause the Group Policy refresh to run as soon as the gpupdate task has been scheduled.

—A value in the range of 1 to the maximum value of 44640 minutes cause the Group Policy refresh to delay the specified number of minutes plus a random offset before starting the Group Policy refresh.

-Sync

Causes the next foreground Group Policy application to be done synchronously. Foreground Group Policy applications occur at computer startup and user logon. You can specify this for the user, computer or both using the Target parameter.

On a client computer, by default, Group Policy processes synchronously at computer startup and asynchronously at user logon.

On a server, by default Group Policy processes synchronously at computer startup and at user logon.

-Target<String>

Specifies that only user or computer policy settings are refreshed. By default, both user and computer policy settings are refreshed. You can specify one of two allowable values for this parameter:

-- User

-- Computer

If the target parameter is not specified both user and computer policy settings will be refreshed.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

• None

  This cmdlet does not take any object as input.

Outputs

The output type is the type of the objects that the cmdlet emits.

• None

  Invoke-GPUpdate does not return an object.

Notes

• The Invoke-GPUpdate cmdlet does not support scheduling a Group Policy refresh for computers running Windows XP or earlier.

• In order to successfully schedule a Group Policy refresh for computers using the Invoke-GPUpdate cmdlet, the following Firewall rules must be set on each client computer to allow the following connections:

  --Remote Scheduled Tasks Management (RPC)

  --Remote Scheduled Tasks Management (RPC-ERMAP)

  --Windows Management Instrumentation (WMI-IN)

Examples

-------------------------- EXAMPLE 1 --------------------------

Description

-----------

This command schedules a Group Policy refresh on the computer on which you are running the Invoke-GPUpdate cmdlet.

PS C:\> Invoke-GPUpdate

-------------------------- EXAMPLE 2 --------------------------

Description

-----------

This command schedules a Group Policy refresh on a remote computer (CONTOSO\COMPUTER-02) which will only schedule to update the user policy settings in synchronous mode.
