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
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.
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”

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?
