In this article, we will discuss 7 commonly used PowerShell scripts for MSPs and how to use them.

1. Get-EventLog

Get-EventLog is a PowerShell cmdlet that retrieves event log entries from local and remote computers. This cmdlet can be used to troubleshoot issues by viewing events in the system, application, security, or any other custom event log. You can filter events based on the event ID, source, or time frame.

To use Get-EventLog, open PowerShell and type the following command:

Get-EventLog -LogName System -EntryType Error -After (Get-Date).AddDays(-7)

This command retrieves all error events from the System event log that occurred in the last 7 days.

2. Get-Process

Get-Process is a PowerShell cmdlet that retrieves information about processes running on a local or remote computer. This cmdlet can be used to monitor CPU and memory usage, find processes that are consuming too many resources, and kill processes that are not responding.

To use Get-Process, open PowerShell and type the following command:

Get-Process | Where-Object {$_.CPU -gt 50}

This command retrieves all processes running on the computer that are using more than 50% CPU.

3. Get-Service

Get-Service is a PowerShell cmdlet that retrieves information about services running on a local or remote computer. This cmdlet can be used to start, stop, or restart services, as well as monitor their status.

To use Get-Service, open PowerShell and type the following command:

Get-Service | Where-Object {$_.Status -eq “Stopped”}

This command retrieves all services that are currently stopped on the computer.

4. Test-NetConnection

Test-NetConnection is a PowerShell cmdlet that checks the network connectivity to a specific destination. This cmdlet can be used to troubleshoot network issues, check if a specific port is open, and test connectivity to a remote server.

To use Test-NetConnection, open PowerShell and type the following command:

Test-NetConnection -ComputerName www.google.com -Port 80

This command checks if port 80 is open on www.google.com.

5. Get-WMIObject

Get-WMIObject is a PowerShell cmdlet that retrieves information from the Windows Management Instrumentation (WMI) repository. This cmdlet can be used to retrieve information about hardware, software, processes, and system settings.

To use Get-WMIObject, open PowerShell and type the following command:

Get-WMIObject -Class Win32_ComputerSystem

This command retrieves information about the computer system, such as the manufacturer, model, and operating system.

6. Export-Csv

Export-Csv is a PowerShell cmdlet that exports data to a CSV file. This cmdlet can be used to export the output of other PowerShell cmdlets to a CSV file, which can be easily opened in Microsoft Excel.

To use Export-Csv, open PowerShell and type the following command:

Get-Service | Export-Csv -Path “C:\services.csv” -NoTypeInformation

This command exports the output of Get-Service to a CSV file located at “C:\services.csv”.

7. Set-ExecutionPolicy

Set-ExecutionPolicy is a PowerShell cmdlet that determines the level of security for running PowerShell scripts. This cmdlet can be used to allow or restrict the execution of PowerShell scripts on a local or remote computer.

To use Set-ExecutionPolicy, open PowerShell and type the following command:

Set-ExecutionPolicy RemoteSigned

This command allows the execution of PowerShell scripts that are signed by a

trusted publisher or that originate from the local computer. It restricts the execution of unsigned scripts downloaded from the internet.
