PowerShell has become one of the most important tools for Windows administrators. Whether you’re managing a handful of computers or thousands of enterprise devices, PowerShell helps you automate repetitive tasks, troubleshoot issues faster, and manage Windows systems more efficiently.

In 2026, PowerShell remains an essential skill for IT professionals, system administrators, cloud engineers, and help desk technicians. With Microsoft’s continued investment in automation, mastering PowerShell can save hours of manual work every week.

In this guide, we’ll explore the most useful PowerShell commands every Windows administrator should know and explain when and why to use them.

Why PowerShell Matters in 2026

Modern IT environments are more complex than ever. Organizations now manage on-premises servers, cloud resources, virtual machines, and remote endpoints simultaneously. Performing these tasks manually isn’t practical.

PowerShell allows administrators to:

• Automate repetitive tasks
• Manage Windows servers remotely
• Generate system reports
• Monitor services and processes
• Configure Active Directory
• Manage Microsoft 365 and Azure
• Troubleshoot systems efficiently

Even administrators who primarily use graphical tools can benefit from learning a few essential PowerShell commands.

1. Get-Help

The first command every administrator should know is:

Get-Help

Need help with a specific command?

Get-Help Get-Service

Want detailed documentation?

Get-Help Get-Service -Full

Instead of searching the web every time, PowerShell provides built-in documentation that explains syntax, parameters, and examples.

2. Get-Command

Not sure which command performs a particular task?

Use:

Get-Command

Search for service-related commands:

Get-Command *service*

This command is extremely useful when you’re learning PowerShell or exploring new modules.

3. Get-Service

To display all Windows services:

Get-Service

Check a specific service:

Get-Service WinRM

Find stopped services:

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

Administrators frequently use this command while troubleshooting server issues.

4. Get-Process

View all running processes:

Get-Process

Find Microsoft Edge:

Get-Process msedge

Sort processes by CPU usage:

Get-Process | Sort-Object CPU -Descending

This helps identify applications consuming excessive system resources.

5. Stop-Process

Terminate an unresponsive application:

Stop-Process -Name notepad

Or by Process ID:

Stop-Process -Id 2456

Always verify the process before stopping it, especially on production servers.

6. Get-ComputerInfo

Need detailed information about a computer?

Get-ComputerInfo

You’ll see:

• Windows version
• BIOS details
• Manufacturer
• RAM
• Processor
• Operating System information

This command is excellent for system inventory and troubleshooting.

7. Test-Connection

Instead of opening Command Prompt for a ping test:

Test-Connection google.com

Check multiple devices:

Test-Connection Server01,Server02

This is especially useful when verifying connectivity across multiple systems.

8. Get-EventLog

View recent System logs:

Get-EventLog System

View the newest entries:

Get-EventLog System -Newest 20

Checking event logs through PowerShell is much faster than manually navigating Event Viewer.

9. Restart-Service

Restart a Windows service:

Restart-Service Spooler

This command is commonly used when fixing printing issues or restarting application services without rebooting the server.

10. Get-ChildItem

Think of this as the PowerShell equivalent of the dir command.

List files:

Get-ChildItem

View another folder:

Get-ChildItem C:\Logs

Include hidden files:

Get-ChildItem -Force

11. Copy-Item

Copy files:

Copy-Item report.txt D:\Backup

Copy an entire folder:

Copy-Item C:\Data D:\Backup -Recurse

Perfect for backup scripts and file management tasks.

12. Remove-Item

Delete files:

Remove-Item old.log

Delete folders recursively:

Remove-Item C:\Temp -Recurse

Use caution with this command because deleted files may not be recoverable.

13. Get-NetIPAddress

Display IP address information:

Get-NetIPAddress

This replaces several older networking commands and provides more detailed output.

14. Get-Disk

Display storage information:

Get-Disk

Useful for checking:

• Disk size
• Health status
• Partition style
• Available drives

15. Get-HotFix

Check installed Windows updates:

Get-HotFix

This command helps administrators verify whether important security patches have been installed.

Best Practices When Using PowerShell

PowerShell is powerful, but it’s important to use it responsibly.

Some best practices include:

• Test scripts in a non-production environment first.
• Run PowerShell with the least privileges necessary.
• Add comments to scripts for easier maintenance.
• Keep PowerShell updated.
• Avoid downloading scripts from unknown sources.
• Back up important data before making large-scale changes.

Following these habits helps reduce mistakes and keeps systems secure.
