Installation updates

Check the installation instructions for your preferred operating system:

Additionally, PowerShell 7.2 supports ARM64 versions of Windows and macOS and ARM32 and ARM64 versions of Debian and Ubuntu.

For up-to-date information about supported operating systems and support lifecycle, see the PowerShell Support Lifecycle.

New universal install packages for Linux distributions

Previously, we created separate installer packages for each supported version of CentOS, RHEL, Debian, and Ubuntu. The universal installer package combines eight different packages into one, making installation on Linux simpler. The universal package installs the necessary dependencies for the target distribution and creates the platform-specific changes to make PowerShell work.

Microsoft Update support for Windows

PowerShell 7.2 add support for Microsoft Update. When you enable this feature, you'll get the latest PowerShell 7 updates in your traditional Windows Update (WU) management flow, whether that's with Windows Update for Business, WSUS, SCCM, or the interactive WU dialog in Settings.

The PowerShell 7.2 MSI package includes following command-line options:

  • USE_MU - This property has two possible values:
    • 1 (default) - Opts into updating through Microsoft Update or WSUS
    • 0 - don't opt into updating through Microsoft Update or WSUS
  • ENABLE_MU
    • 1 (default) - Opts into using Microsoft Update the Automatic Updates or Windows Update
    • 0 - don't opt into using Microsoft Update the Automatic Updates or Windows Update

Experimental Features

The following experimental features are now mainstream features in this release:

The following experimental feature was added in this release:

  • PSNativeCommandArgumentPassing - When this experimental feature is enabled PowerShell uses the ArgumentList property of the StartProcessInfo object rather than our current mechanism of reconstructing a string when invoking a native executable. This feature adds a new automatic variable $PSNativeCommandArgumentPassing that allows you to select the behavior at runtime.

  • PSAnsiRenderingFileInfo - Allow ANSI color customization of file information.

  • PSLoadAssemblyFromNativeCode - Exposes an API to allow assembly loading from native code.

For more information about the Experimental Features, see Using Experimental Features.

Improved Tab Completions

PowerShell 7.2 includes several improvements to Tab Completion. These changes include bugfixes and improve usability.

  • Fix tab completion for unlocalized about* topics (#15265) (Thanks @MartinGC94)
  • Fix splatting being treated as positional parameter in completions (#14623) (Thanks @MartinGC94)
  • Add completions for comment-based help keywords (#15337) (Thanks @MartinGC94)
  • Add completion for Requires statements (#14596) (Thanks @MartinGC94)
  • Added tab completion for View parameter of Format-* cmdlets (#14513) (Thanks @iSazonov)

PSReadLine 2.1 Predictive IntelliSense

PSReadLine 2.1 introduced CommandPrediction APIs that establish a framework for providing predictions for command-line completion. The API enables users to discover, edit, and execute full commands based on matching predictions from the user's history.

Predictive IntelliSense is disabled by default. To enable predictions, run the following command:

Set-PSReadLineOption -PredictionSource History

Separating DSC from PowerShell 7 to enable future improvements

The PSDesiredStateConfiguration module was removed from the PowerShell 7.2 package and is now published to the PowerShell Gallery. This allows the PSDesiredStateConfiguration module to be developed independently of PowerShell and users can mix and match versions of PowerShell and PSDesiredStateConfiguration for their environment. To install PSDesiredStateConfiguration 2.0.5 from the PowerShell Gallery:

Install-Module -Name PSDesiredStateConfiguration -Repository PSGallery -MaximumVersion 2.99

Important

Be sure to include the parameter MaximumVersion or you could install version 3 (or higher) of PSDesireStateConfiguration that contains significant differences.
