Service management (Get/Start/Stop-Service) in PowerShell - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the <code>Get-Service</code> cmdlet do in PowerShell?

It lists all the services on your computer or shows details about a specific service if you provide its name.

How do you start a service named 'Spooler' using PowerShell?

Use the command Start-Service -Name Spooler to start the 'Spooler' service.

intermediate

What happens if you try to stop a service that is already stopped using Stop-Service?

PowerShell will not throw an error; it simply ensures the service is stopped. If the service is already stopped, nothing changes.

Run Get-Service -Name wuauserv. It shows if the service is Running, Stopped, or Paused.

intermediate

Can you start or stop multiple services at once using PowerShell? How?

Yes, by passing an array of service names to Start-Service or Stop-Service, like Start-Service -Name 'Spooler','wuauserv'.

Which PowerShell cmdlet lists all services on your computer?

A Stop-Service

B Start-Service

C Get-Service

D Restart-Service

Get-Service shows all services and their status.

What does Start-Service -Name 'Spooler' do?

A Starts the Spooler service

B Gets the status of the Spooler service

C Restarts the Spooler service

D Stops the Spooler service

This command starts the service named 'Spooler'.

If you want to stop a service, which cmdlet should you use?

A Stop-Service

B Get-Service

C Start-Service

D Enable-Service

Stop-Service stops a running service.

How do you check if a service is running or stopped?

A Use <code>Restart-Service</code>

B Use <code>Start-Service</code>

C Use <code>Stop-Service</code>

D Use <code>Get-Service</code>

Get-Service shows the current status of services.

Can you start multiple services at once in PowerShell?

A No, only one service at a time

B Yes, by listing service names in an array

C Yes, but only with <code>Get-Service</code>

D No, you must use a loop

You can pass multiple service names as an array to Start-Service or Stop-Service.

Explain how to check the status of a service and then start it if it is stopped using PowerShell.

Think about first seeing if the service is stopped, then starting it.

Describe how you would stop multiple services at once using PowerShell commands.

Consider how to pass more than one service name to the cmdlet.

Practice

1. What does the PowerShell command Get-Service do?

easy

A. It shows the status of services on the computer.

B. It starts a stopped service.

C. It stops a running service.

D. It deletes a service from the system.

Solution

1. Step 1: Understand the purpose of Get-Service

   The Get-Service command lists services and their current status (running or stopped).

2. Step 2: Compare with other commands

   Start-Service and Stop-Service change service states, but Get-Service only shows status.

3. Final Answer:

   It shows the status of services on the computer. -> Option A

4. Quick Check:

   Get-Service = Show service status [OK]

Hint: Get-Service always lists service status, not start or stop [OK]

Common Mistakes:

• Confusing Get-Service with Start-Service
• Thinking Get-Service stops services
• Assuming Get-Service deletes services

2. Which of the following is the correct syntax to start a service named 'Spooler' in PowerShell?

easy

A. Start-Service -Name Spooler

B. Get-Service -Start Spooler

C. Stop-Service -Name Spooler

D. Start-Service Spooler -Force

Solution

1. Step 1: Identify the correct cmdlet for starting a service

   Start-Service is used to start services, and it accepts the -Name parameter to specify the service.

2. Step 2: Check the syntax correctness

   Start-Service -Name Spooler is the correct syntax. Get-Service -Start Spooler uses wrong cmdlet and parameter, Stop-Service -Name Spooler stops service, and Start-Service Spooler -Force uses an invalid parameter -Force.

3. Final Answer:

   Start-Service -Name Spooler -> Option A

4. Quick Check:

   Start-Service -Name ServiceName = Start service [OK]

Hint: Use Start-Service with -Name to start a service [OK]

Common Mistakes:

• Using Get-Service to start a service
• Using Stop-Service instead of Start-Service
• Adding invalid parameters like -Force

3. What will be the output of this PowerShell command?

Get-Service -Name W32Time | Select-Object -Property Status

medium

A. Starts the W32Time service.

B. Displays the status (Running or Stopped) of the W32Time service.

C. Stops the W32Time service.

D. Shows an error because Select-Object cannot be used here.

Solution

1. Step 1: Understand Get-Service with Select-Object

   Get-Service -Name W32Time fetches the service object, and piping it to Select-Object -Property Status extracts only the status property.

2. Step 2: Determine the output

   The output will be a simple display showing the status of the W32Time service, such as Running or Stopped.

3. Final Answer:

   Displays the status (Running or Stopped) of the W32Time service. -> Option B

4. Quick Check:

   Get-Service + Select-Object = Show service status [OK]

Hint: Get-Service piped to Select-Object shows specific properties [OK]

Common Mistakes:

• Thinking it starts or stops the service
• Believing Select-Object causes an error here
• Confusing service name with command parameters

4. You run this command to stop the 'Spooler' service:

Stop-Service Spooler

But it fails with an error. What is the likely cause?

medium

A. You need to specify the parameter name: -Name before the service name.

B. The service is already stopped, so Stop-Service cannot run.

C. Stop-Service cannot stop the Spooler service.

D. You must run PowerShell as Administrator to stop services.

Solution

1. Step 1: Check command syntax

   Stop-Service Spooler is valid because the parameter -Name is positional and can be omitted.

2. Step 2: Consider permissions

   Stopping services usually requires administrator rights. Without running PowerShell as admin, the command fails with an error.

3. Final Answer:

   You must run PowerShell as Administrator to stop services. -> Option D

4. Quick Check:

   Stopping services needs admin rights [OK]

Hint: Run PowerShell as admin to stop services [OK]

Common Mistakes:

• Thinking -Name parameter is mandatory
• Assuming service must be running to stop
• Believing Spooler service cannot be stopped

5. You want to write a script that checks if the 'W32Time' service is stopped, and if so, starts it. Which script snippet correctly does this?

hard

A. Start-Service -Name W32Time -IfStopped

B. if (Get-Service W32Time -Status 'Stopped') { Start-Service W32Time }

C. $svc = Get-Service -Name W32Time
if ($svc.Status -eq 'Stopped') { Start-Service -Name W32Time }

D. $svc = Get-Service W32Time
if ($svc.Status = 'Stopped') { Start-Service W32Time }

Solution

1. Step 1: Retrieve the service object and check status

   Using $svc = Get-Service -Name W32Time stores the service object. Then $svc.Status -eq 'Stopped' correctly compares the status.

2. Step 2: Start the service if stopped

   If the status is 'Stopped', Start-Service -Name W32Time starts the service.

3. Final Answer:

   $svc = Get-Service -Name W32Time if ($svc.Status -eq 'Stopped') { Start-Service -Name W32Time } -> Option C

4. Quick Check:

   Check status with -eq, then start service [OK]

Hint: Use -eq to compare status, then Start-Service if stopped [OK]

Common Mistakes:

• Using single = instead of -eq for comparison
• Assuming Start-Service has -IfStopped parameter
• Trying to filter Get-Service with -Status parameter
