Top Essential Windows PowerShell Commands You Need to Boost Your Productivity (And Their Benefits Explained)

PowerShell is a powerful tool for anyone dealing with messy folders or needing to automate tasks. I use it to organize client files and manage old code. While it’s popular among IT admins, anyone can benefit from its commands.

PowerShell combines a command-line shell with a scripting language, making it a versatile option for automating tasks. In recent updates, Windows Terminal has become the go-to for running PowerShell and other shell environments.

One of the first commands people learn is Get-Help. This command is a must for newcomers. It provides details about any cmdlet (command-let), including how to use it. Just type:

Get-Help Get-Process

This gives you a summary, syntax, and even examples of how to use the Get-Process command.

Then, there’s Get-Command. It helps you find and list all available commands. If you’re unsure of the command name, this command can guide you. For example:

Get-Command *process*

This will list every command that includes the word “process.”

Another useful cmdlet is Test-NetConnection. This command checks if a website is reachable, combining several network tools into one. For example, you can check if a server is up and trace its route:

Test-NetConnection example.com

Need to test a specific port? Just add it to the command:

Test-NetConnection server.company.com -Port 443

If you’re looking for files, Get-ChildItem will help you list files in a directory. Want to find PDFs modified in the last week? Use:

Get-ChildItem -Path C:\Users\YourName\Documents -Filter *.pdf | Where-Object { $_.LastWriteTime -gt (Get-Date).AddDays(-7) }

PowerShell’s Where-Object helps filter results based on specific criteria—it acts like an “if” statement. If you want to find running processes that consume a lot of memory:

Get-Process | Where-Object { $_.WorkingSet -gt 100MB }

A significant strength of PowerShell is the ability to combine commands. For instance, you can pipe results from one command to another. If you want to see only the names and statuses of services, just run:

Get-Service | Select-Object Name, Status

To see what properties an object has, you can use Get-Member. For example:

Get-Process | Get-Member

This will show various details about the running processes, such as their properties and methods.

Copying output to your clipboard can sometimes be tricky. The cmdlets Set-Clipboard and Get-Clipboard simplify this. You can copy command results like this:

Get-Process | Select-Object Name, CPU | Set-Clipboard

For a visual representation of data, use Out-GridView. It creates a window with a sortable and filterable table, perfect for analyzing large datasets with ease:

Get-Process | Out-GridView

Finally, Get-Process provides insights into all running programs on your computer, letting you quickly identify memory and CPU usage. If your computer is slow, you can find the culprits using:

Get-Process | Sort-Object WorkingSet -Descending | Select-Object -First 10

PowerShell is a rich system for automation and organization, and learning its commands is a game changer for anyone looking to streamline tasks.
