PowerShell is a powerful scripting language and command-line shell designed specifically for system administration tasks in Windows environments. One of its many uses is to gather detailed information about Windows services. This article will guide you through the process of using PowerShell to obtain information about the services running on a Windows system.

Examples:

Example 1: Listing All Services

To list all services on a Windows machine, you can use the Get-Service cmdlet. This command retrieves the status of all services installed on the system.

Get-Service

This command will output a list of all services, displaying their status (Running, Stopped, etc.), name, and display name.

Example 2: Filtering Services by Status

If you want to filter services by their status, such as only displaying running services, you can use the Where-Object cmdlet in combination with Get-Service.

Get-Service | Where-Object { $_.Status -eq 'Running' }

This command will list only the services that are currently running.

Example 3: Getting Detailed Information About a Specific Service

To obtain detailed information about a specific service, use the Get-Service cmdlet followed by the service name.

Get-Service -Name 'wuauserv'

This command will provide detailed information about the Windows Update service, including its status, service type, and dependent services.

Example 4: Exporting Service Information to a File

You can export the list of services and their statuses to a CSV file for further analysis using the Export-Csv cmdlet.

Get-Service | Export-Csv -Path "C:\ServicesList.csv" -NoTypeInformation

This command will create a CSV file at the specified path containing the details of all services.

Example 5: Checking Dependencies of a Service

To check which services depend on a specific service, you can use the Get-Service cmdlet with the -DependentServices parameter.

(Get-Service -Name 'wuauserv').DependentServices

This command will list all services that depend on the Windows Update service.
