Updated: April 21, 2010

Applies To: Windows PowerShell 2.0

Suspends (pauses) one or more running services.

Syntax

Suspend-Service [-Name] <string[]> [-Exclude <string[]>] [-Include <string[]>] [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Suspend-Service -DisplayName <string[]> [-Exclude <string[]>] [-Include <string[]>] [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Suspend-Service [-InputObject <ServiceController[]>] [-Exclude <string[]>] [-Include <string[]>] [-PassThru] [-Confirm] [-WhatIf] [<CommonParameters>]

Description

While suspended, the service is still running, but its action is halted until resumed, such as by using Resume-Service. You can specify the services by their service names or display names, or you can use the InputObject parameter to pass a service object representing the services that you want to suspend.

<CommonParameters>

This command supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, OutBuffer, OutVariable, WarningAction, and WarningVariable. For more information, see about_CommonParameters.

Inputs and Outputs

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

 

Inputs

System.ServiceProcess.ServiceController or System.String

You can pipe a service object or a string that contains a service name to Suspend-Service.

Outputs

None or System.ServiceProcess.ServiceController

When you use the PassThru parameter, Suspend-Service generates a System.ServiceProcess.ServiceController object representing the service. Otherwise, this cmdlet does not generate any output.

Notes

Suspend-Service can control services only when the current user has permission to do so. If a command does not work correctly, you might not have the required permissions.

Also, Suspend-Service can suspend only services that support being suspended and resumed. To determine whether a particular service can be suspended, use the Get-Service cmdlet with the CanPauseAndContinue property. For example, "Get-Service wmi | Format-List name, canpauseandcontinue". To find all services on the computer that can be suspended, type "Get-Service | Where-Object {$_.canpauseandcontinue -eq "True"}".

To find the service names and display names of the services on your system, type "Get-Service". The service names appear in the Name column, and the display names appear in the DisplayName column.

Example 1

C:\PS>suspend-service -displayname "Telnet"

Description

-----------

This command suspends the Telnet service (Tlntsvr) service on the local computer.

Example 2

C:\PS>suspend-service -name lanman* -whatif

Description

-----------

This command tells what would happen if you suspended the services that have a service name that begins with "lanman". To suspend the services, rerun the command without the WhatIf parameter.

Example 3

C:\PS>get-service schedule | suspend-service

Description

-----------

This command uses the Get-Service cmdlet to get an object that represents the Task Scheduler (Schedule) service on the computer. The pipeline operator (|) passes the result to the Suspend-Service cmdlet, which suspends the service.

Example 4

C:\PS>get-service | where-object {$_.canpauseandcontinue -eq "True"} | suspend-service -confirm

Description

-----------

This command suspends all of the services on the computer that can be suspended. It uses the Get-Service cmdlet to get objects representing the services on the computer. The pipeline operator (|) passes the results to the Where-Object cmdlet, which selects only the services that have a value of "True" for the CanPauseAndContinue property. Another pipeline operator passes the results to the Suspend-Service cmdlet. The Confirm parameter prompts you for confirmation before suspending each of the services.
