We’re excited to announce the General Availability of PowerShell 7.7, the next Standard Term Support
(STS) release of PowerShell. PowerShell 7.7 is built on .NET 11, continuing the alignment between
PowerShell and the modern .NET platform.
PowerShell 7.7 focuses on security hardening, new and improved commands, and reliability across the
engine, remoting, and interactive shell experience.
Notable areas of improvement include:
- Security hardening across Constrained Language Mode, remoting, and help
- New commands and parameters
- More predictable handling of switch parameters
- Startup, tab completion, and file system fixes
- Module updates
For support dates, see the PowerShell support lifecycle article.

A quick example
New-TemporaryDirectory creates a uniquely named directory in the system temp folder and returns a
DirectoryInfo object. Use -Prefix to make the directory easier to recognize:
# Create a uniquely named directory in the system temp folder
$workDir = New-TemporaryDirectory -Prefix build
$workDir.FullName
# Remove it when you're done
Remove-Item -LiteralPath $workDir.FullName -RecurseBreaking changes
PowerShell 7.7 includes a small number of breaking changes. Review them before you upgrade
production scripts.
New-Guidgenerates version 7 (time-sortable) UUIDs by default instead of version 4. Use
[guid]::NewGuid()when you need a fully random GUID.Format-Table,Format-List, andFormat-Customnow validate that-Propertyis not null or
empty.- Null-or-empty argument validation now throws
System.ArgumentException. - Explicit false values for
Where-Objectoperator switches, such as-EQ:$false, are now handled correctly.
Other behavior changes
These changes might also affect existing scripts:
- The update notification feature was removed from PowerShell.
Test-Jsonrequires-FetchExternalReferenceto resolve external schema references.Export-Csvno longer accepts-Appendtogether with-NoHeader. Using-NoTypeInformation
on the CSV cmdlets now writes a deprecation warning and has no effect.Get-ChildItem -Namewith-Recursenow returns matching files in subdirectories when the path
contains a wildcard or names a file.- Constrained Language Mode restricts property assignment on non-core objects, including through
ForEach().
