Windows PowerShell and command prompt (CMD) are both essential command-line interface tools for Windows administrators, allowing them to execute commands, manage system processes and automate administrative tasks. While CMD has been a foundational component of Windows since the MS-DOS era, PowerShell has emerged as a more advanced and powerful scripting language, enhancing system management and automation capabilities.
This blog provides a detailed comparison between PowerShell and CMD, highlighting their strengths and weaknesses and examining practical examples and key differences. The goal is to help Windows professionals understand when to choose one tool over the other.
What is PowerShell?
PowerShell is a powerful command-line interface and scripting language, primarily aimed at system administrators and IT professionals. PowerShell was designed to automate administrative tasks, manage configurations, and provide detailed control over the Windows operating system and its components.
One of the defining characteristics of PowerShell is its object-oriented nature. Because PowerShell is built on top of .NET framework. PowerShell commands (known as cmdlets) return objects rather than plain text output. Each object contains properties and methods, which represent the actions that can be performed on the object.
PowerShell’s close integration with the .NET framework means that users can leverage a vast library of classes, methods and properties. PowerShell is also designed to work seamlessly with Windows Management Instrumentation (WMI), which provides a powerful way of accessing system management information. WMI allows PowerShell to retrieve system properties, manage hardware components and interact with the operating system at a deeper level.
What is Command Prompt (CMD)?
CMD is a command-line interpreter available in Windows operating systems that allows users to run Windows commands and scripts for file management, directory navigation and system configuration. Its simplicity makes it an ideal choice for users who need to perform basic tasks without the complexity of an advanced scripting language.
A key feature of CMD is its capability to run batch files. A batch file is a script file containing a series of commands that are executed sequentially, this way users can automate repetitive tasks, such as backing up files, modifying system settings, or installing applications.
CMD provides direct access to operating system features and configurations. Users can access system settings, network configurations and execute system commands without navigating through a GUI, which can be more efficient for certain tasks, especially troubleshooting. CMD allows access to system environment variables like %PATH%, %TEMP% and %USERNAME%, which are used to define system settings and configurations and can be referenced in commands and scripts.
Key Differences Between PowerShell and (CMD) Command Prompt
PowerShell and command prompt are designed with different functionalities and user needs in mind. Below is a detailed feature comparison that highlights the key differences.
| Feature | PowerShell | Command Prompt (CMD) |
| Cross-platform availability | The PowerShell Core (v7 and later) edition of PowerShell works on Windows, Linux and macOS. | CMD is limited to Windows environments only. |
| Command help and community support | PowerShell offers detailed, structured help for cmdlets, functions and scripts, including examples, via the Get-Help cmdlet. It also has extensive online documentation and an active community, offering troubleshooting, tutorials and advanced use cases. | CMD provides basic information and options about command syntax via the Help command but lacks in-depth guidance. CMD’s community is smaller than that of PowerShell, and its documentation is less comprehensive. |
| Output types | PowerShell outputs .NET objects, which can be easily manipulated, so it is suitable for more advanced processing of data and complex operations. | CMD outputs plain text. While you can use redirection or piping, all output is a simple stream of characters, making it less flexible for complex data manipulation. |
| Command chaining | PowerShell supports advanced command chaining using pipes (|), which allow passing of objects between cmdlets for complex workflows. | CMD allows basic chaining using operators like (|), but only text is passed between commands. This limits the types of operations you can perform. |
| Scripting capabilities | PowerShell uses .ps1 scripts with advanced scripting elements like functions, loops and conditional statements, making it ideal for automation. | CMD supports batch scripting with simple command sequences. It is suitable for basic automation and file management tasks. Scripts are written in .bat files. |
| Object manipulation | PowerShell is excellent at manipulating objects due to its object-oriented nature, allowing for efficient handling of different data types and complex tasks. | CMD is limited to text manipulation and lacks the ability to handle structured data easily, so more complex commands are required for similar outcomes. |
| Remote management | PowerShell has built-in capabilities for executing commands remotely, making it an essential tool for system administrators managing multiple machines. | CMD has limited remote management options, so external tools or scripts are needed for remote operations. |
| User interface | PowerShell supports a richer user interface with features like tab completion, syntax highlighting and access to Windows Presentation Foundation (WPF) for graphical elements. | CMD has a basic user interface with no advanced features like tab completion or syntax highlighting, so it often requires more exact command input. |
| Command aliases and flexibility | PowerShell includes cmdlet aliases (like gci for Get-ChildItem), making it more user-friendly. | CMD does not have many aliases and its command syntax is more rigid. |
| Error handling | PowerShell has advanced and structured error handling using try, catch and finally. This allows for better control and debugging of errors. | CMD offers limited error handling via if error level, which is less useful and not as user-friendly as PowerShell’s approach. |
| Task automation | PowerShell’s object-oriented nature and full scripting language makes it excellent for automating complex workflows, system administration and bulk operations across machines. | CMD’s batch scripting is suitable for smaller, straightforward automation tasks, like file management or system diagnostics. |
| Cross-platform scripting | PowerShell scripts can be executed on Windows, Linux and macOS, making it a versatile choice for system administrators working across platforms. | CMD batch files (.bat) are exclusive to Windows, limiting their use in cross-platform environments. |
| Ease of use | PowerShell is more complex; its advanced capabilities mean there is a steeper learning curve. For basic tasks, users may find it overkill. | CMD is simpler, which makes it easier for beginners and other users to perform straightforward tasks like navigating directories or listing files. |
| Troubleshooting/network testing | PowerShell provides advanced cmdlets for detailed network diagnostics, such as Test-Connection (which is like ping but more powerful) and Get-NetIPAddress. | CMD is preferred for network testing because commands like ping, ipconfig, tracert and netstat are lightweight. |
Why CMD Still Matters
Despite PowerShell’s dominance in system administration and automation, CMD still remains valuable in certain situations, such as the following:
- Many legacy systems and applications still rely on CMD and batch files for functionality. With CMD, batch files are easy to create and edit.
- CMD’s simplicity makes it ideal for basic tasks such as file management, where it offers a quick and straightforward approach. It provides direct access to system operations with minimal overhead.
- CMD is particularly useful for quick operations when Windows is not fully operational, such as performing diagnostics or repairs.
- While PowerShell can handle network-related tasks, CMD’s simplicity makes it faster for basic commands. For example, the ping, tracert and ipconfig commands often used by network administrators enables quick troubleshooting and offer immediate, easy-to-read feedback.
Overall, CMD is still a practical tool for straightforward tasks that don’t require the complexity of PowerShell.

Windows Recovery and Safe Mode Operations
CMD is frequently used in Windows Recovery Environment (WinRE) to troubleshoot and fix issues when the operating system is not booting properly. In recovery mode, CMD can be used to perform system repairs and restoration tasks that would otherwise require a GUI. For example, CMD can be used to:
- Fix bootloader issues and repair the Master Boot Record (MBR). Resolve boot-related issues preventing Windows from starting.
- Restore the system if it fails to boot or has become unstable. Access system restore points from the command prompt to restore the system to a previous state.
- Fix problems related to booting or missing operating systems in dual-boot setups. Modify or rebuild the Boot Configuration Data (BCD) store.
PowerShell and CMD: Practical Examples
When it comes to administrative tasks in Windows, both PowerShell and the command prompt are powerful tools, but they handle tasks differently. Below, we compare the difference between PowerShell and CMD when it comes to three common administrative tasks: creating user accounts, querying event logs and performing file operations.
Creating User Accounts
PowerShell
With PowerShell, you can use New-LocalUser to create a local machine user, and New-ADUser to create user accounts in Active Directory, as follows:
New-LocalUser -Name "John.Doe" -Password (ConvertTo-SecureString "Password123#" -AsPlainText -Force) -FullName "John Doe" -Description "A new user account"
New-ADUser -Name "Josh Brolin" -Path "OU=NBC,DC=milkyway,DC=local" -GivenName "Josh" -Surname "Brolin" -SamAccountName "Josh-Brolin" -AccountPassword (ConvertTo-SecureString -AsPlainText “webdir123R” -Force ) -ChangePasswordAtLogon $True -DisplayName "Josh Brolin" -Enabled $True
CMD
To create a user account from CMD, use the net user command, as shown in these examples:
net user john.doe P@ssw0rd /add
net user John.Doe Password123# /add /fullname:"John Doe" /comment:"A new user account"
Querying Event Logs
PowerShell
PowerShell provides cmdlets specifically designed to retrieve event logs, making it quite powerful for this task. For instance, you can use either of the following commands to get the last 10 entries from the System and Application event logs:
Get-EventLog -LogName System -Newest 10
Get-EventLog -LogName Application -EntryType Error -Newest 10
CMD
In CMD, querying event logs requires using the wevtutil command, which is less user-friendly. Here is the command to get the last 10 entries from the System event log:
wevtutil qe System /c:10 /f:text
Performing File Operations
Both PowerShell and CMD enable copying, moving and deleting files, but PowerShell provides more advanced features, such as handling file properties.
PowerShell
PowerShell provides cmdlets like Copy-Item, Move-Item and Remove-Item to manage files, as illustrated here:
Copy-Item -Path "C:\Logs\Log1.txt" -Destination "C:\Backup\Log1.txt"
Move-Item -Path "D:\Backup\Log1.txt" -Destination "E:\Archive\Log1.txt"
Remove-Item -Path "E:\Archive\Log1.txt" -Force
CMD
In CMD, you can use the copy, move and del commands for file operations:
copy C:\Logs\Log1.txt C:\Backup\Log1.txt
move D:\Backup\Log1.txt E:\Archive\Log1.txt
del E:\Archive\Log1.txt
Transitioning from CMD to PowerShell
Key Concepts to Understand
Command prompt users who want to take advantage of the more robust capabilities of PowerShell need to understand the following key points before converting their scripts.
- Command structure — CMD uses executable commands like dir and copy, while PowerShell uses cmdlets that follow a verb-noun structure, such as Get-ChildItem and Copy-Item.
- Object-oriented — PowerShell deals with objects rather than plain text, which enables more complex data manipulation.
- Pipeline — PowerShell’s pipeline feature allows you to pass objects between cmdlets, enabling chaining of commands.
Learning Basic PowerShell Cmdlets
Start with some basic cmdlets that have CMD equivalents, like those in the table below. Take time to practice these and other fundamental cmdlets.
| Task | CMD Command | PowerShell Cmdlet |
| List directory contents | dir | Get-ChildItem |
| Copy a file | copy | Copy-Item |
| Move a file | move | Move-Item |
| Delete a file | del | Remove-Item |
| View network configuration | ipconfig | Get-NetIPConfiguration |
| Change current directory | cd | Set-Location |
| Ping a server | ping | Test-Connection |
Converting CMD Batch Scripts to PowerShell Scripts
To convert CMD scripts to PowerShell, convert each CMD command to its PowerShell equivalent. However, remember that while some basic commands in batch scripts will translate directly to PowerShell, there are important differences in syntax and capabilities. In addition, remember that CMD batch scripts are typically saved with the .bat extension, while PowerShell scripts are saved with the .ps1 extension.
For example, here is a CMD batch script:
@echo off
echo Copying file...
copy C:\Temp\Log1.txt D:\Backup\
echo Done!
And here is the equivalent PowerShell script:
Write-Host "Copying file..."
Copy-Item -Path "C:\Temp\Log1.txt" -Destination "D:\Backup\"
Write-Host "Done!"
