Learn to display your current PowerShell version with this short guide

It’s easy to find out which version of PowerShell you are using on Windows 10 and 11. You can check the version by running simple commands, using the registry, or by signing in remotely. This wikiHow article will show you how to check your PowerShell version and teach you how to upgrade PowerShell to the latest version.

  1. Open PowerShell.
  2. Type $PSVersionTable and press Enter.
  3. Find the PowerShell version next to “PSVersion.”

  1. Step 1 Open PowerShell.

    There are multiple ways that you can run PowerShell:

    • Press the Win key and search for PowerShell, and then click the system result.
    • Press Win + X to open a menu and click PowerShell. However, you can change “PowerShell” here to “Command Prompt,” so this method may not work for you.
    • This is the easiest and fastest method to find your PowerShell version.

  2. Step 2 Type $PSVersionTable into PowerShell and press ↵ Enter.

    Pressing Enter sends the command.

  3. Step 3 Look for your PowerShell version number.

    It’s next to “PSVersion”.

    • Version 5.1 is the last supported Microsoft version, so that’s most likely what your updated computer has.
    • You can also use the commands get-host and $host.version, but those are less likely to give accurate answers. Use the $PSVersionTable command for the best results.

  1. Step 1 Open Registry Editor.

    Press the Win key, type regedit, and click the app result.

  2. Step 2 Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.

    You can enter that into the address bar or navigate the different folders.

  3. Step 3 Check your version of PowerShell.

    Look for subfolders that indicate your version of PowerShell.

    • For example, PowerShell 5 is in PowerShell\3\PowerShellEngine.
    • PowerShell 7 is in PowerShellCore\InstalledVersions\31ab5147-9a97-4452-8443-d9709f0516e1.

  1. Step 1 Run winrm quickconfig on the remote computer as an Administrator.

    You need to do this so the computer will let you use PowerShell remotely.

  2. Step 2 Type the following command and press ↵ Enter:

  3. Step 3 Look for the PowerShell version number.

    It’s next to “PSVersion”.

  1. To upgrade PowerShell, you'll need to update Windows.

    By updating Windows, you’ll also update your PowerShell version if you have an out-of-date one.

    • This method will not update you to PowerShell 7. To get that version, you can find it in Github where you can download the version for your OS.[2]

Are you a PowerShell pro? If not, then it’s useful to understand how to check your PowerShell version as a beginner. In this detailed guide, we’ll explain how to check PowerShell easily.

Key Take Away

  • In this article, we explore four simple methods to check the PowerShell version.
  • Most of the methods are easy and quickly offer the solution.
  • PowerShell is a tool for IT professionals to manage and automate administrative tasks.

How to Check Your PowerShell Version

Let’s easily check what version of PowerShell is installed on your device.

  • Go to the Start menu, search ‘powershell’, and Launch PowerShell.

After launching PowerShell, you will get a screen like the one below:

Now, here we’ll use some of the commands to check the PowerShell version.

Let’s discuss 4 ways to check the Windows 11 PowerShell version.

The Get-Host command

Let’s use the primary command in PowerShell to find out the version. The command is: get-host.

But what is get-host? Here, the host is a program hosting the PowerShell engine. It means the get-host command returns the host version.

As you can see below, the command displays information like the name of the host, current culture, and UI culture.

The PowerShell version mentioned below is 5.1.22621.2506.

The $host.Version command

If you run the command $host.Version or (Get-Host).Version, You will get a similar result as we got with the get-host command.

The $PSVersionTable command

This is the most reliable method to check the PowerShell version in your system. Like the above three, it’s a simple command: $PSVersionTable, and press Enter. This command will also display a list of information. The first one on the list is the PowerShell version, in this case, it is 5.1.

The $PSVersionTable returns specific information about the PowerShell engine version. It also displays the edition running on your system — core or desktop, to define the PowerShell edition. You can use this read-only automatic variable on a remote computer.

The Registry

In this method, you can use the Registry Editor to check the PowerShell version in your system.

Now, there are two ways to identify the PowerShell version using the Registry Editor:

  • One, you can simply type in the command
  • Two, you can open the Registry Editor app to find the PowerShell version.
(Get-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine -Name 'PowerShellVersion').PowerShellVersion

Now, you have to click a few boxes to check the PowerShell version in your system.

  1. First, click the Software folder under HKEY-LOCAL-MACHINE, or HKLM folder.
  2. Now, search Microsoft in the software vendors list.
  3. Click the Microsft folder and search PowerShell
  4. Under PowerShell, there will be two folders: 1 and 3, click on 3.
  5. Then select PowerShell Engine
  6. On the right, you’ll see a list of information along with the PowerShell version.

That’s it. These are the four ways to check the PowerShell version installed in your system.

How to check the PowerShell version on your remote computer?

Here, you can change the computer name with your specific computer name, and voila! It will return the PowerShell version information.

Key Takeaways
 To check the version of PowerShell you are using on Windows 10, open a PowerShell window and enter “$PSVersionTable” into the prompt. The current PowerShell version will be displayed next to “PSVersion.”
 Finding your PowerShell version helps you know what PowerShell features you have access to. A PowerShell command lets you reveal the version number, and we’ll show you how to do this.
Find Your PowerShell Version
 You’ll use the PowerShell utility itself to find the version number.
 To start, open the “Start” menu, search for “Windows PowerShell,” and click it in the search results.
Search for "PowerShell" in the Start Menu.  
$PSVersionTable
Enter "$PSVersionTable" to see your PowerShell version.  
 PowerShell displays various numbers. Here, the first value that says “PSVersion” is your PowerShell version.
The version of PowerShell you're currently using will be the first entry.  
 You can now close the PowerShell window.
How to Get PowerShell 7 Version
 To check your PowerShell 7 version on Windows 10, just open up PowerShell 7 and look at the very first line in the window. It prints the PowerShell version every time you open a new instance.
PowerShell 7 displays the version number every time you open it.  
$PSVersionTable

Get PowerShell Version with the get-host Command
 Only use this if you’re checking your
 
 local 
 
 PowerShell version.
 To use the get-host command to check your PowerShell version, open up any version of PowerShell, then enter:
get-host
The results of get-host in PowerShell 7.  
Find PowerShell Version Using the $Host variable
 The $host variable is automatically set when you open PowerShell, all we need to do is query the version. Once again, open up PowerShell, then enter:
$host.version
 You’ll see your version number displayed in a neat little table.
The output of $host. Version.  
 You can also just run $host if that is more to your liking, but it contains additional information that you may not care about, much like the get-host command.
The full output from the $host command.  
Check Your PowerShell Version in the Windows Registry
 You can also check your PowerShell version from the Windows registry. First, open up the Start Menu, then search for and launch “Regedit.”
Open the Registry Editor through the Start Menu.  
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft
 Scroll down through the list until you see the PowerShell listings. As you might expect, PowerShell 5 and PowerShell 7 are in slightly different locations. It is also possible that future iterations will be stored in slightly different locations. If our specific paths don’t work, just look around through the PowerShell keys until you find entries that talk about versions. They’ll be very similar to the examples we attached below.
 PowerShell 5 is located in:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine
 Then check the “PowerShellVersion” entry to get your exact version number.
The Registry entry for PowerShell 5.  
 PowerShell 7 is directly below in our case (and likely will be for you too). The version information can be found in:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShellCore\InstalledVersions\31ab5147-9a97-4452-8443-d9709f0516e1​​​​​​​
 Your PowerShell 7 version is displayed next to the “SemanticVersion” entry.
The PowerShell 7 version displayed in the Registry.  
Update PowerShell in Windows 10
 Windows 10 updates the built-in PowerShell tool when you install system updates. This means that you should keep your PC up to date to ensure that you’re always running the latest version of PowerShell.
 Also, know that PowerShell 7 is different from the version that’s usually installed on Windows 10 PCs. To install this version of PowerShell, either download the installer file or run a command from PowerShell on your PC.

While working with files in PowerShell, you may get requirements to check if a file contains a specified string. PowerShell provides different methods to check if a file contains a string. Let us check each method with examples.
To check if a file contains a specific string in PowerShell, you can use the Select-String cmdlet with the -Pattern parameter specifying your search term, and the -Path parameter to define the file’s location. For a simple true or false return, add the -Quiet switch. For example: $containsString = Select-String -Path “C:\MyFolder\MyFile.txt” -Pattern “searchTerm” -Quiet will return True if “searchTerm” is found, otherwise False.
I am using Visual Studio code to execute all the PowerShell scripts. You can also use Windows PowerShell ISE to execute the examples.
And for each method, I will take a .txt file.
Now, let us check various methods of PowerShell to check if a file contains a specific string.
1. Using the Select-String Cmdlet
The Select-String cmdlet in PowerShell is similar to the grep command in Unix or Linux. This command you can use to search for text patterns within files. It uses regular expression matching to search for text patterns in input strings and files.
Here’s a simple example of how to use Select-String in PowerShell to check if a file contains a specific string.
Select-String -Path "C:\MyFolder\MyFile.txt" -Pattern "powershellfaqs"
This command searches for the string “powershellfaqs” in the file “MyFile.txt” located in “C:\MyFolder”. If the string is found, Select-String will return the line or lines containing the string, along with some additional context information.
The screenshot below shows that this file contains the string twice and displays both lines.
Check if a File Contains a String in PowerShell
2. Check for a String in Multiple Files in PowerShell
Sometimes, you may want to check for a sting in all the files in the folder, and this is easy to do in PowerShell.
To check for a specific string across multiple files in PowerShell, you can combine Get-ChildItem with Select-String:
Get-ChildItem -Path "C:\MyFolder\*.txt" | Select-String -Pattern "powershellfaqs"
This script searches for “powershellfaqs” in all text files within “C:\MyFolder”. It lists any files containing the string, along with the lines where the string was found.
3. Using the -Quiet Switch
This is another simple method if you just want to know if the string is presented in the file or not in PowerShell. It just returns true or false.
If you only need to know whether the string exists in the file and don’t need to see the specific lines, you can use the -Quiet switch in PowerShell. This will return a boolean value: True if the string is found, and False otherwise.
$containsString = Select-String -Path "C:\MyFolder\MyFile.txt" -Pattern "powershellfaqs" -Quiet
$containsString
Here, you can see the output in the screenshot below; it returns true as the string is presented in the file.
How to Check if a File Contains a String in PowerShell
4. Checking if a String Exists with -match Operator
Here is also another method to check if a string exists within a file is to use the -match operator in PowerShell. First, you’ll need to read the file content into a variable and then use -match to search for the string.
$content = Get-Content -Path "C:\MyFolder\MyFile.txt"
$containsString = $content -match "powershellfaqs"
This approach is useful when you want to perform additional operations on the file content after checking for the string.
5. Using .Contains() Method
This is another simple method to check if a string contains in a file in PowerShell. In PowerShell, you can use the .Contains() method on a string object. After reading the file into a variable, you can check if the string contains your specified term.
$content = Get-Content -Path "C:\MyFolder\MyFile.txt" -Raw
$containsString = $content.Contains("powershellfaqs")
Note that .Contains() is case-sensitive. For a case-insensitive search, you can convert both the content and the search term to the same case using .ToLower() or .ToUpper().
Here is the PowerShell script for case-insensitive search.
$content = Get-Content -Path "C:\MyFolder\MyFile.txt" -Raw
$lowercaseContent = $content.ToLower()
$containsString = $lowercaseContent.Contains("powershellfaqs".ToLower())
6. Using -like Operator with Wildcards
In PowerShell, the -like operator allows you to use wildcards for pattern matching. This can be useful when you want to check if a string contains a specific word or pattern.
$content = Get-Content -Path "C:\MyFolder\MyFile.txt"
$containsString = $content -like "*powershell*"
The asterisks * are wildcards that represent any number of characters. This command will return True if “powershell” is found anywhere in the content.
7. Using Regular Expressions
In PowerShell, you can also use regular expressions to do a pattern-matching search. You can use regular expressions with Select-String. This allows you to search for complex patterns within the text.
Select-String -Path "C:\MyFolder\MyFile.txt" -Pattern "powershell\w+"
Conclusion
PowerShell provides several methods to check if a file contains a specific string or pattern. In this PowerShell tutorial, I have explained with examples how to check if a file contains a string using the below methods:
  1. Using the Select-String Cmdlet
  2. Check for a String in Multiple Files in PowerShell
  3. Using the -Quiet Switch
  4. Checking if a String Exists with -match Operator
  5. Using .Contains() Method
  6. Using -like Operator with Wildcards
  7. Using Regular Expressions
