Stop Windows Services with PowerShell

Windows PowerShell Stop-Service Cmdlet

This page will show you how to stop a Windows service.  If you prefer we can easily modify the script to Restart the service.  If you need a grounding in the PowerShell syntax associated with this ‘Service’ family of commands, I recommend that you begin with my Get-Service page.

PowerShell’s Stop-Service Topics

 ♣

Preliminary Script to List Services Which Are Running

Stopping the wrong service could have disastrous effects on a server, especially if you append the -force parameter.  This is why I suggest that you run this script and select a less important service such as Bits, Spooler or Themes

# PowerShell script to list running services
Clear-Host
Get-WmiObject Win32_Service |
Where-Object {$_.State -eq ‘Running’} |
Format-Table name, state, status -auto

Learning Points

Note 1: To highlight the modular nature of this script I have written it on three lines.  The first pipeline gets a list of Windows services, the second pipeline uses a where statement to filter Running services, while the final line merely formats the output.

Example 1: How to Stop a Windows Service

I have chosen the 'Themes' service as a vehicle to test the stop service command.  However, you may wish to substitute a different value for $SrvName.

# PowerShell cmdlet to stop the named service "Themes"
Clear-Host
$SrvName = "Themes"
$SrvName + " is now " + (Get-Service $SrvName).status
Stop-Service $SrvName
$SrvName + " is now " + (Get-Service $SrvName).status

Note 2: Naturally, for a production script you could simplify to:

# Production script to stop a service
Stop-Service -name "Themes"

Note 3: To restart a service, simply change the verb from 'Stop' to 'Restart' thus:

# Production restart service
Clear-Host
Restart-Service -name "Themes"

Guy Recommends:  A Free Trial of the Network Performance Monitor (NPM)Review of Orion NPM v11.5 v11.5

SolarWinds’ Network Performance Monitor will help you discover what’s happening on your network.  This utility will also guide you through troubleshooting; the dashboard will indicate whether the root cause is a broken link, faulty equipment or resource overload.

What I like best is the way NPM suggests solutions to network problems.  Its also has the ability to monitor the health of individual VMware virtual machines.  If you are interested in troubleshooting, and creating network maps, then I recommend that you try NPM now.

Example 2: Stop Service Safety Procedure

Before you stop a service, especially if this is the first time, and you are not familiar with its dependencies, I suggest you run this script.

# PowerShell script to check service dependencies
#Clear-Host
Get-Service | Where-Object {$_.DependentServices.count -gt 0} |
Format-Table Name, @{Label="Number"; Expression={$_.dependentservices.count}} -auto

Note 4: This script employs Get-Service (rather than Stop-Service) to lists all services with more than one dependent.  See more on the $_ variable.

Example 3: Stop Service – Force Parameter

# PowerShell cmdlet to force a service to stop
Clear-Host
$SrvName = "Themes"
$SrvName + " is now " + (Get-Service $SrvName).status
Stop-Service $SrvName -force
$SrvName + " is now " + (Get-Service $SrvName).status

Note 5: While -force probably is not needed for the Themes service, there maybe times when you need this power.  However, don’t abuse the -force parameter or else your server may stop functioning in the way that you intended.

Engineer's Toolset v10Guy Recommends: SolarWinds Engineer’s Toolset v10

This Engineer’s Toolset v10 provides a comprehensive console of 50 utilities for troubleshooting computer problems.  Guy says it helps me monitor what’s occurring on the network, and each tool teaches me more about how the underlying system operates.

There are so many good gadgets; it’s like having free rein of a sweetshop.  Thankfully the utilities are displayed logically: monitoring, network discovery, diagnostic, and Cisco tools.  Try the SolarWinds Engineer’s Toolset now!

More Research for Stop-Service Parameters

Before we use the -force parameter, let us see how we can research all the parameters for a cmdlet.

# Research Stop-Service parameters
Clear-Host
Get-Help Stop-Service -full

Note 6: This was how I discovered -force was available for this parameter.

Note 7: For 'Dependencies', turn Get-Help on the sister cmdlet Get-Service

Stop Service Example

Here is an example designed to stop a service, but with a built-in wait command before continuing.

Scenario: You want a script to stop a service then shutdown the computer.

# This script stops the Print Spooler service.
# However, it will wait while the service is stopping ….

$ServiceName = 'Print Spooler'
Stop-Service $ServiceName
Write-Host $ServiceName'…' -NoNewLine
$TestService = Get-Service $ServiceName
While($TestService | Where-Object {$_.Status -eq 'Running'}){
Write-Host '.'-NoNewLine
Start-Sleep 3
}
Write-Host "`n$ServiceName stopped"

Note 8: To see the effect alter $ServiceName to $ServiceNamexxx.

SolarWinds Response Time Viewer for WiresharkGuy Recommends: Response Time Viewer for Wireshark

Here is a free tool to troubleshoot network connection and latency problems.  Key concept: this is a free tool from SolarWinds that analyzes network packets captured by Wireshark (also a free tool).

When you inspect the data in the Response Time Dashboard, if you hover over an application such as Teredo or TCP, then you get an orange box showing a breakdown of network and application response times, note the 'Peak value' in addition to the 'Average'.

Remoting with Services

One aspect of remoting in PowerShell v 2.0 is simply to append -computerName xyz to the command that you ran on the local machine.  For further research try:

Clear-Host
Get-Command | Where { $_.parameters.keys -Contains "ComputerName"}

Surprise!  Get-Service is amongst the cmdlets that support remoting, but stop, start and Restart-Service are not on the list.  More bad news, stop, start and Restart-Service really don’t work on network machines.  Thus you have to employ different techniques such as Get-WmiObject and InvokeMethod.  Alternatively, you could enter-PSSession and then run Restart-Service as if you were on the local machine.  However, to get that working you have to first install and setup WinRM

The Service Family (Each member has a different verb)

Get-Service:  Useful for listing the services
Set-Service:  Crucial parameter -startuptype
Start-Service:  The verb ‘start’ says it all
Stop-Service:  Handy for scripts which prevent unwanted services running e.g. Telnet
Restart-Service:  A nice touch by the creator’s of PowerShell; this cmdlet removes the need to explicitly stop then start the service.

Summary of PowerShell’s Stop-Service Cmdlet

This page will show you how to stop a Windows service.  If circumstances demand, then you could modify the script to force a stop even thought there are dependent services.
