How to Install and Update PowerShell 7
The PowerShell team just announced PowerShell 7. PowerShell 7 is built on .NET Core 3 and brings back many APIs required by modules built on .NET Framework so that they work with .NET Core runtime. While PowerShell Core 6 was focusing on bringing cross-platform compatibility, PowerShell 7 will focus on making it a viable replacement for Windows PowerShell 5.1 and bringing near parity with Windows PowerShell. Here is how you can install and update PowerShell 7 on Windows and Linux using a simple one-liner.
If you want to know what’s new in PowerShell 7, check out my blog post!
One great example of how cross-platform PowerShell can work, check out my blog post: How to set up PowerShell SSH Remoting.
Install PowerShell 7
Before showing you the one-liner option to install PowerShell 7, I want to share with you the documentation to install PowerShell 7 on different operating systems like Windows, macOS, and Linux.
- Installing PowerShell Core on Windows
- Installing PowerShell Core on Linux
- Installing PowerShell Core on macOS
- Installing PowerShell Core on ARM
One-liner to install or update PowerShell 7 on Windows 10
Steve Lee (Microsoft Principal Software Engineer Manager in the PowerShell Team) shared some one-liner, which helps you quickly install and update:
You can use this single command in Windows PowerShell to install PowerShell 7.
iex "& { $(irm https://aka.ms/install-powershell.ps1) } -UseMSI"
There are additional switches to, for example, install daily builds of the latest PowerShell previews.
-Destination
The destination path to install PowerShell Core to.
-Daily
Install PowerShell Core from the daily build.
Note that the ‘PackageManagement’ module is required to install a daily package.
-Preview
Install the latest preview, which is currently version 7.
-UseMSI
Use the MSI installer.
-Quiet
The quiet command for the MSI installer.
-DoNotOverwrite
Do not overwrite the destination folder if it already exists.
-AddToPath
On Windows, add the absolute destination path to the ‘User’ scope environment variable ‘Path’;
On Linux, make the symlink ‘/usr/bin/pwsh’ points to “$Destination/pwsh”;
On MacOS, make the symlink ‘/usr/local/bin/pwsh’ points to “$Destination/pwsh”.
One-liner to install or update PowerShell 7 on Linux
You can use this as a single command to install PowerShell 7 on Linux.
wget https://aka.ms/install-powershell.sh; sudo bash install-powershell.sh; rm install-powershell.sh
Depending on your distro you are using, this will register Microsoft’s pkg repos and install that package (deb or rpm).
You can also use the following switches:
-includeide
Installs VSCode and VSCode PowerShell extension (only relevant to machines with a desktop environment)
-interactivetesting
Do a quick launch test of VSCode (only applicable when used with -includeide)
-skip-sudo-check
Use sudo without verifying its availability (hard to accurately do on some distros)
-preview
Installs the latest preview release of PowerShell side-by-side with any existing production releases
To currently run the PowerShell Preview, you can run the following command:
pwsh
After Installing
After you have installed PowerShell 7, also make sure to update PowerShellGet and the PackageManagement module.
I hope this blog post was helpful. If you have any questions, please let me know in the comments.
You can also use my PSReleaseTools module (https://github.com/jdhitsolutions/PSReleaseTools) which is in the PowerShell Gallery. It works cross platform and you can easily download setup files. Here’s how you could download and install the 64bit msi for Windows 10:
Get-PSReleaseAsset -Preview -Family Windows -Only64Bit | where format -eq ‘msi’ | Save-PSReleaseAsset -Path d:\ -Passthru | Invoke-Item
Hi Thomas,
How do I update or install PowerShelll 7 in disconnected environment ? These are machines with no outside connectivity.
Thanks,
Hi, In that case, you just download the MSI installer from GitHub and copy it to the machine :)
https://github.com/powershell/powershell You have a download table, make sure you for PowerShell 7, that you download the preview version.
Was so happy I can finally install the MSOnline module but Powershell 7 can’t get seem to get passed a “Could not load type ‘System.Security.Cryptography.SHA256Cng” error when I try to Connect-MSOnlineService . Hopefully they can get passed it by the time it becomes GA.
If you are on a Linux system that supports snaps you can install both the current and preview versions of Powershell from the Snap store.
e.g. for Powershell 6 – sudo snap install powershell –classic
and for Powershell 7 – sudo snap install powershell-preview –classic
Note that these snaps are published by Microsoft. Also the –classic flag is required as the snaps are published with classic confinement.
Is powershell 7 currently available for MAC Sierra edition? Thank you
Thanks Thomas
Is it possible to add powershell 7 to winPE?
Can PowerShell 7 be used to “upgrade” Powershell 5.1 on Server 2016 or are they dual-installed given 5.1 is Windows centric while v7 is mutli-source OS based?
Hi Steve! Windows PowerShell 5.1 and PowerShell 7 are side-by-side installations. (Like PowerShell Core 6 and Windows PowerShell 5.1)
I must do something wront ;'(
PS C:\Windows\system32> iex “& { $(irm https://aka.ms/install-powershell.ps1) } -UseMSI”iex “& { $(irm https://aka.ms/install-powershell.ps1) } -UseMSI”
Invoke-Expression : A positional parameter cannot be found that accepts argument ‘iex’.

Ah, I was pasting the url encoded ampersand (& amp ;) from the blog here. Replace with just the ampersand (&) and bingo!
Sorry for that, my CMS sometimes tries to fix my code ;)
Thanks easy install!
For MDT or SCCM you could also use:
msiexec.exe /package PowerShell-7.0.0-win-x64.msi /quiet ADD_EXPLORER_CONTEXT_MENU_OPENPOWERSHELL=1 ENABLE_PSREMOTING=1 REGISTER_MANIFEST=1
How does one replace PS 5.1 right click context ‘run with PowerShell’ so that it points to 7?
Thanks for this. I wonder if there is an easy way to make PowerShell 7 the default from the Windows right click menu? TIA.
I’d like to install PS 7 and Visual Studio Code with AWS Tools on Win 10. What’s the best way to set this combo up?
It is just crashing after the launch

I love this command and use it all the time!
I discovered the issue with your command and the pic of the powershell window above shows what went wrong.
Your command below the pic is this: (wrong) iex “& { $(irm https://aka.ms/install-powershell.ps1) } -UseMSI” (wrong)
The part that is missing is the -Preview at the end of the command. The working command is:
(working) iex “& { $(irm https://aka.ms/install-powershell.ps1) } -UseMSI -Preview” (working)
Thank you for the post! As an IT professional, I find Powershell to be a major time and life saver and is a requirement to learn for any serious Windows Support Professional.
Thank you Jeremy
For the command without -Preview works fine. If you add -Preview it will install the latest preview which right now I think is 7.1.
However, I will check :)
Hey Thomas, the code to copy still contains amp; after the & symbol.
Thanks, Marc
Something changes it when the blog gets updated. I fixed it again.
Thank you so much.
