DESCRIPTION
The Start-Service cmdlet sends a start message to the Windows Service Controller for each of the specified services
. If a service is already running, the message is ignored without error. You can specify the services by their serv
ice names or display names, or you can use the InputObject parameter to supply a service object representing the se
rvices that you want to start.

Specifies the display names of the services to be started. Wildcards are permitted.

Required? true
Position? named

pattern, such as "s*". Wildcards are permitted.

Required? false
Position? named
Default value
Accept pipeline input? false

-Include
Starts only the specified services. The value of this parameter qualifies the Name parameter. Enter a name elem
ent or pattern, such as "s*". Wildcards are permitted.

Required? false
Position? named

-InputObject
Specifies ServiceController objects representing the services to be started. Enter a variable that contains the
objects, or type a command or expression that gets the objects.

Required? false
Position? named
Default value
Accept pipeline input? true (ByValue)
Accept wildcard characters? false

-Name
Specifies the service names for the service to be started.

The parameter name is optional. You can use "-Name" or its alias, "-ServiceName", or you can omit the parameter
name.

Required? true
Position? 1
Default value
Accept pipeline input? true (ByValue, ByPropertyName)

Accept wildcard characters? false


This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer and OutVariable. For more information, type,
"get-help about_commonparameters".

INPUTS
System.ServiceProcess.ServiceController, System.String
You can pipe objects that represent the services or strings that contain the service names to Start-Service.


OUTPUTS
None or System.ServiceProcess.ServiceController
When you use the PassThru parameter, Start-Service generates a System.ServiceProcess.ServiceController object r
epresenting the service. Otherwise, this cmdlet does not generate any output.


NOTES


You can also refer to Start-Service by its built-in alias, "sasv". For more information, see about_Aliases.

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

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

You can start only the services that have a start type of "Manual" or "Automatic". You cannot start the service
s with a start type of "Disabled". If a Start-Service command fails with the message "Cannot start service vice-name> on computer," use a Get-WmiObject command to find the start type of the service and, if necessary, u
se a Set-Service command to change the start type of the service.

Some services, such as Performance Logs and Alerts (SysmonLog) stop automatically if they have no work to do. W
hen Windows PowerShell starts a service that stops itself almost immediately, it displays the following message
: "Service start failed."


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

C:\PS>start-service -name eventlog


Description
-----------
This command starts the EventLog service on the local computer. It uses the Name parameter to identify the service
by its service name.





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

C:\PS>start-service -displayname *remote* -whatif


Description
-----------
This command tells what would happen if you started the services with a display name that includes "remote". It use
s the DisplayName parameter to specify the services by their display name instead of by their service name. And, it
uses the WhatIf parameter to tell what would happen if the command were executed instead of executing the command.





-------------------------- EXAMPLE 3 --------------------------

C:\PS>$s = get-service wmi

C:\PS>start-service -InputObject $s -passthru | format-list >> services.txt


Description
-----------
These commands start the Windows Management Instrumentation (WMI) service on the computer and add a record of the a
ction to the services.txt file. The first command uses the Get-Service cmdlet to get an object representing the WMI
service and store it in the $s variable.

The second command uses the Start-Service cmdlet to start the WMI service. It identifies the service by using the I
nputObject parameter to pass the $s variable containing the WMI service object to Start-Service. Then, it uses the
PassThru parameter to create an object that represents the starting of the service. Without this parameter, Start-S
ervice does not create any output.

The pipeline operator (|) passes the object that Start-Service creates to the Format-List cmdlet, which formats the
object as a list of its properties. The append redirection operator (>>) redirects the output to the services.txt
file, where it is added to the end of the existing file.





-------------------------- EXAMPLE 4 --------------------------

C:\PS># start-service


Description
-----------
This series of commands shows how to start a service when the start type of the service is "Disabled". The first co
mmand, which uses the Start-Service cmdlet to start the Telnet service (tlntsvr), fails.

C:\PS>start-service tlntsvr

Start-Service : Service 'Telnet (TlntSvr)' cannot be started due to the following error: Cannot start service Tl
ntSvr on computer '.'.
At line:1 char:14
+ start-service <<<< tlntsvr

The second command uses the Get-WmiObject cmdlet to get the Tlntsvr service. This command retrieves an object with
the start type property in the StartMode field. The resulting display reveals that the start type of the Tlntsvr se
rvice is "Disabled".

C:\PS> get-wmiobject win32_service | where-object {$_.Name -eq "tlntsvr"}

ExitCode : 0
Name : TlntSvr
ProcessId : 0
StartMode : Disabled
State : Stopped
Status : OK

The next command uses the Set-Service cmdlet to change the start type of the Tlntsvr service to "Manual".

C:\PS> set-service tlntsvr -startuptype manual

Now, we can resubmit the Start-Service command. This time, the command succeeds.

C:\PS> start-service tlntsvr

To verify that the command succeeded, use Get-Service.
