PowerShell is different because it works with objects instead of just text. Objects are like data packages that contain useful details and built-in actions. This makes it easier to pass information between commands, filter results, and automate tasks without extra work. <\/div>\r\n<\/div>\n
How to Download Windows PowerShell<\/h2>\n
\nPowerShell comes pre-installed on Windows 10 and Windows 11, so if you’re using one of these versions, you likely don’t need to install it separately. However, if you want the latest features, you can update to the newest PowerShell version.<\/p>\n
For users on older Windows versions, like Windows 7 or 8, downloading and installing PowerShell manually is necessary. Here is how to do it with WinGet:\n<\/p>\n
- \n
- Search for Command Prompt<\/em> and click Run as administrator<\/em>.<\/li>\n<\/ul>\n\r\n\r\n
![\"Search]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- Run the following WinGet command:<\/li>\n<\/ul>\n
winget install --id Microsoft.PowerShell --source winget<\/pre>\n
\r\n\r\n![\"Run]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- If prompted, accept the installation agreement. WinGet will download and install PowerShell automatically.<\/li>\n<\/ul>\n
How to Configure PowerShell<\/h2>\n
\nAfter installing PowerShell, you need to configure it properly to ensure it is secure and to improve its performance. Below are the key steps to get started:<\/p>\n
Set your preferred execution policy<\/strong><\/p>\n
By default, PowerShell enforces restrictions <\/a> on running scripts. While this is good for security reasons, you need to make some changes before you can start running scripts.<\/p>\n
First, you need to check your current execution policy. Open PowerShell, and run the following command:\n<\/p>\n
Get-ExecutionPolicy<\/pre>\n
\nIf the command executes successfully, it will return one of the following values:\n<\/p>\n
- \n
- Restricted:<\/b> No scripts are allowed to run (default on Windows 11).<\/li>\n
- RemoteSigned:<\/b> Locally created scripts can run, but downloaded scripts must be signed.<\/li>\n
- Unrestricted:<\/b> All scripts can run, but you will get a warning for downloaded scripts.<\/li>\n
- AllSigned:<\/b> Only scripts signed by a trusted publisher can run.<\/li>\n
- Bypass:<\/b> No restrictions; all scripts run without warnings (not recommended for security).<\/li>\n<\/ul>\n
\r\n\tFor most users, the best option is RemoteSigned because it allows scripts created on your PC to run while requiring downloaded scripts to be signed. This helps prevent malicious scripts from executing while still allowing automation. <\/div>\r\n<\/div>\nIf needed, you can change the policy by running this command:\n<\/p>\n
Set-ExecutionPolicy RemoteSigned<\/pre>\n
\nAfter making this change, PowerShell will allow your trusted scripts to run while maintaining protection against unverified sources.<\/p>\n
Updating PowerShell<\/strong>\n<\/p>\n
- \n
- In Windows Search, type Command Prompt <\/i> and click Run as administrator. <\/i><\/li>\n<\/ul>\n\r\n\r\n
![\"Search]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- Next, enter the following command and hit
Enter<\/code>:<\/li>\n<\/ul>\nwinget upgrade --id Microsoft.PowerShell --source winget<\/pre>\n
\r\n\r\n![\"Run]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- Windows will check for available updates and prompt you to continue. Type Y <\/i> and press
Enter<\/code> <\/i>if required.<\/li>\n<\/ul>\nShould you use PowerShell ISE or Terminal?<\/strong><\/p>\n
When you search for Windows PowerShell, you will notice there are different options; click any of them to start PowerShell.<\/p>\n
\r\n\r\n![\"When]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nEach of these options serves a different purpose. Here’s how they differ:\n<\/p>\n
- \n
- Open: <\/b>This option launches PowerShell in normal user mode with standard permissions. It allows you to run scripts, manage system settings, and interact with Windows features, but with limited privileges.<\/li>\n
- Run as Administrator<\/b>:<\/strong> With this option, you can open PowerShell with administrator privileges. This means you can run some Windows PowerShell commands like modifying system policies or installing software that won’t work in normal mode.<\/li>\n
- Run ISE as Administrator: This is a graphical user interface (GUI) version of PowerShell. It includes features like syntax highlighting, tab completion, and debugging tools, making it easier to write and test scripts. Like with the regular PowerShell, it allows running scripts that require administrative rights. <\/b><\/li>\n
- Windows PowerShell ISE<\/b>:<\/strong> This is the same ISE (Integrated Scripting Environment) but without elevated privileges.<\/li>\n<\/ul>\n
Core PowerShell Commands<\/h2>\n
\nWe start with core PowerShell commands, which are the basic commands for controlling your computer and managing tasks. They’re simple, built-in instructions that allow you to start working with PowerShell easily and effectively.<\/p>\n
Get-Command<\/strong><\/p>\n
With this, you can get a list of all available Windows PowerShell commands. It is useful when searching for a specific command or discovering available functions, cmdlets, or aliases. For example, inputting Get-Command -Module ActiveDirectory<\/em> will list all commands available in the ActiveDirectory module.<\/p>\n
\r\n\r\n![\"Inputting]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nGet-Help<\/strong><\/p>\n
The Get-Help<\/em> command <\/a> provides information about other PowerShell commands to help you understand their usage. It can also come in handy for professionals during troubleshooting as you can use it to get quick documentation on commands.<\/p>\n
For example, let’s say you need to know how the Copy-Item<\/em> command works. You can type Get-Help Copy-Item <\/i> to see a detailed explanation of its parameters and examples of how to use it.<\/p>\n
\r\n\r\n![\"The]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nGet-Item<\/strong><\/p>\n
The Get-Item<\/em> command retrieves information about a specific file, folder, or other item in PowerShell. It is useful when you need to inspect the properties of an object before performing actions on it.<\/p>\n
Try the following code (remember to replace directory_path<\/em> with the actual path you want to check):\n<\/p>\n
Get-Item \"C:\\directory_path\"\r\n<\/pre>\n
\r\n\r\n![\"The]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n- \n
- The Mode<\/em> column shows d—–<\/em>, where d<\/em> indicates it is a directory (folder).<\/li>\n
- LastWriteTime<\/em> tells you when the folder was last modified.<\/li>\n
- The Name<\/em> column lists the folder name (scripts<\/em>).<\/li>\n
- There is no Length<\/em> value because folders do not have a file size like individual files do.<\/li>\n<\/ul>\n
Get-Member<\/strong><\/p>\n
The Get-Member<\/em> command displays the properties and methods of an object in PowerShell. It is particularly useful when working with objects whose structure or available actions are unknown.<\/p>\n
Unlike Get-Item<\/em>, this command does not retrieve objects but instead analyzes them, displaying their properties and methods.<\/p>\n
Let’s use the command on the same folder to see the difference (again, replace directory_path<\/em> with the actual path):\n<\/p>\n
Get-Item \"C:\\directory_path\" | Get-Member<\/pre>\n
\nNow, you can access the attributes of the folder, like its Name<\/em>, and available methods for manipulation.<\/p>\n
\r\n\r\n![\"The]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nWorking with Files and Directories<\/h2>\n
\nManaging files and directories is another fundamental part of using PowerShell. With built-in commands, you can create, modify, move, and delete files or folders efficiently. These commands help automate file management tasks, making it easier to organize and control your system’s data.<\/p>\n
Set-Location (cd)<\/b><\/p>\n
The Set-Location<\/em> command, also known as cd<\/em>, is used to change the current directory in PowerShell.<\/p>\n
By default, when you run PowerShell commands, they run in the current directory (usually the user’s home directory, such as C:\\Users\\Username <\/i> on Windows), meaning any file operations or script executions will be relative to this location.<\/p>\n
For example, run the following command (replace C:\\Users\\… <\/i>with the desired directory path):\n<\/p>\n
Set-Location C:\\Users\\HP\\OneDrive\\Desktop\\Scripts<\/pre>\n
\nWindows PowerShell will change the directory you are working in, so you can start working with the files inside it. Notice how the path (in green) changes after the command.<\/p>\n
\r\n\r\n![\"The]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nGet-ChildItem<\/strong><\/p>\n
The Get-ChildItem<\/em> command lists the contents of a directory, including files and subdirectories. Assuming you want to see all files in your desktop folder, you can run the following command (remember to replace C:\\Users\\…<\/em> with the desired path):\n<\/p>\n
Get-ChildItem C:\\Users\\HP\\OneDrive\\Desktop<\/pre>\n
\r\n\r\n![\"The]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nThis is useful for quickly checking file structures or identifying missing files in a directory.<\/p>\n
Copy-Item (cp) <\/strong><\/p>\n
The Copy-Item<\/em> command allows you to copy files and directories from one location to another.<\/p>\n
Let’s say you need to move one of the documents from the desktop to Documents. You can use the following command (replace the source and destination paths with the desired ones):\n<\/p>\n
Copy-Item -Path C:\\Users\\YourUsername\\Desktop\\Document.txt -Destination C:\\Users\\YourUsername\\Documents\\<\/pre>\n
\r\n\r\n![\"The]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nRemove-Item (rm) <\/b><\/p>\n
Like the name suggests, the Remove-Item<\/em> command deletes files and folders. System administrators often use this to clean up outdated or unnecessary files.<\/p>\n
Let’s assume you have an old log file named oldlog.txt<\/em> in the Documents folder. You can easily use the following command (remember to replace C:\\Users\\…<\/em> with the desired path to the file):\n<\/p>\n
Remove-Item C:\\Users\\HP\\OneDrive\\Documents\\oldlog.txt<\/pre>\n
\r\n\r\n![\"the]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\r\n\tWarning<\/div>\r\n\tBe cautious when using it, as deleted files may not be easily recoverable, though it is not impossible. If you have accidentally removed crucial files, there are ways you can use to recover deleted files <\/a> on your Windows PC using recovery tools like Auslogics File Recovery or Recuva. <\/div>\r\n<\/div>\r\n\nGet-Content<\/b><\/p>\n
The Get-Content<\/em> command retrieves the content of a specified file for reading logs, configuration files, or scripts. It can display the file contents in the console, return an array of strings, or process the content line by line. This command supports filtering and selecting specific lines, making it ideal for handling large files efficiently.<\/p>\n
Imagine you were going through your files with the Get-ChildItem <\/i>command . <\/i>Then, if you spot a file and you are not sure what it is, you can use the following command to see what’s in the file (replace C:\\Users\\…<\/em> with the desired path to the file):\n<\/p>\n
Get-Content -Path \"C:\\Users\\HP\\OneDrive\\Documents\\oldlog.txt\"<\/pre>\n
\r\n\r\n![\"The]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nAs you can see, the command will read the contents and display them in the console. Suppose you only want to read a few lines. You can limit the results by using the arguments First<\/em> or Last<\/em>:\n<\/p>\n
Get-Content -Path \"C:\\Users\\HP\\OneDrive\\Documents\\oldlog.txt\" -First 2<\/pre>\n
\nThis will show you the first 2 lines (replace C:\\Users\\…<\/em> with the desired path to the file and the number with the desired number of lines).<\/p>\n
\r\n\r\n![\"You]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nGet-Content -Path \"C:\\Users\\HP\\OneDrive\\Documents\\oldlog.txt\" - Last 2<\/pre>\n
\nThis will show you the last 2 lines:<\/p>\n
\r\n\r\n![\"This]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nAdd-Content<\/b><\/p>\n
Add-Content<\/em> appends content to a file without overwriting existing data. It is useful for logging, updating configuration files, or adding data to reports.<\/p>\n
Let’s use this command to add a new line of text to our file:\n<\/p>\n
Add-Content -Path \" C:\\Users\\HP\\OneDrive\\Documents\\oldlog.txt\" -Value \"Here is the new line we added.\"<\/pre>\n
\r\n\r\n![\"Use]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nTo see if the line is added, we can use Get-Content<\/em> and the – Last 2 <\/i> argument we covered above:<\/p>\n
\r\n\r\n![\"To]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nSet-Content<\/b><\/p>\n
Set-Content<\/em> writes or replaces content in a file. It is useful for modifying configuration files or creating logs. Unlike Add-Content<\/em>, which appends data, Set-Content<\/em> removes everything in the file and replaces it with your new entry.<\/p>\n
Let’s say the contents of the oldlog.txt<\/em> file have become outdated. We can change the contents by running the following command:\n<\/p>\n
Set-Content -Path \"C:\\Users\\HP\\OneDrive\\Documents\\oldlog.txt\" -Value \"This is the new log entry containing new details. We updated it together, remember?\"<\/pre>\n
\r\n\r\n![\"Set-Content]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nNow, if we check the content of the file (using Get-Content<\/em>), it only has the new text we added.<\/p>\n
\r\n\r\n![\"Now,]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nRename-Item<\/b><\/p>\n
Rename-Item<\/em> renames files or directories. It is beneficial for bulk renaming scripts or restructuring directories. For example, let’s rename our log file as Newlog.txt<\/em>:\n<\/p>\n
Rename-Item -Path \"C:\\Users\\HP\\OneDrive\\Documents\\oldlog.txt\" -NewName \"Newlog.txt\"<\/pre>\n
\r\n\r\n![\"Rename-Item]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nTest-Path<\/b><\/p>\n
Test-Path<\/em> verifies whether a file or directory exists. It returns True<\/em> if the path exists and False<\/em> otherwise, making it useful for conditional execution in scripts.<\/p>\n
Let’s use the command to check if Oldlog.txt<\/em> still exists:\n<\/p>\n
Test-Path -Path \"C:\\Users\\HP\\OneDrive\\Documents\\Oldlog.txt\"<\/pre>\n
\r\n\r\n![\"Test-Path]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nSystem Administration Commands<\/h2>\n
\nSystem administration commands in PowerShell help in monitoring system performance, troubleshooting issues, and automating administrative tasks.<\/p>\n
Most system administration PowerShell commands need admin privileges because they change system settings, processes, and services, which can impact stability and security. To run them, open PowerShell as an administrator.<\/p>\n
\r\n\r\n![\"Open]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nTo be sure PowerShell is running with admin privileges, the window should read Administrator: Windows PowerShell. <\/i><\/p>\n
\r\n\r\n![\"To]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nNow that you have opened PowerShell as an admin, let’s run some commands.<\/p>\n
Get-Service<\/b><\/p>\n
Get-Service<\/em> lists installed services and their statuses. It is useful for monitoring system performance and troubleshooting. For instance, if Windows Update is not working <\/a>, you can check it using the following command:\n<\/p>\n
Get-Service -Name \"wuauserv\"<\/pre>\n
\r\n\r\n![\"if]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nStart-Service \/ Stop-Service<\/b><\/p>\n
These Windows PowerShell commands start and stop system services, which are essential for maintenance and troubleshooting tasks.<\/p>\n
Let’s use the same Windows Update as an example. One of the methods to troubleshoot Windows Update is to stop and then start the service again. You can do that using:\n<\/p>\n
Stop-Service -Name \"wuauserv\"<\/pre>\n
\r\n\r\n![\"One]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nStart-Service -Name \"wuauserv\"<\/pre>\n
- LastWriteTime<\/em> tells you when the folder was last modified.<\/li>\n
- Run as Administrator<\/b>:<\/strong> With this option, you can open PowerShell with administrator privileges. This means you can run some Windows PowerShell commands like modifying system policies or installing software that won’t work in normal mode.<\/li>\n
- Open: <\/b>This option launches PowerShell in normal user mode with standard permissions. It allows you to run scripts, manage system settings, and interact with Windows features, but with limited privileges.<\/li>\n
- Windows will check for available updates and prompt you to continue. Type Y <\/i> and press
- Next, enter the following command and hit
- RemoteSigned:<\/b> Locally created scripts can run, but downloaded scripts must be signed.<\/li>\n
- Restricted:<\/b> No scripts are allowed to run (default on Windows 11).<\/li>\n
- If prompted, accept the installation agreement. WinGet will download and install PowerShell automatically.<\/li>\n<\/ul>\n
- Run the following WinGet command:<\/li>\n<\/ul>\n
