)
Windows PowerShell
Desired State Configuration
(
DSC
) is a new management system in
Windows PowerShell
4.0 that enables the deployment and management of configuration data for software services, and the environment in which these services run. For more information about
DSC
, see Get Started with
Windows PowerShell
Desired State Configuration
.
Save-Help now lets you save help for modules that are installed on remote computers. You can use Save-Help to download module Help from an Internet-connected client (on which not all of the modules for which you want help are necessarily installed), and then copy the saved help to a remote shared folder, or a remote computer that does not have Internet access.
The
Windows PowerShell
debugger has been enhanced to allow debugging of
Windows PowerShell
workflows, as well as scripts that are running on remote computers.
Windows PowerShell
workflows can now be debugged at the script level from either the
Windows PowerShell
command line or
Windows PowerShell
ISE
.
Windows PowerShell
scripts, including script workflows, can now be debugged over remote sessions. Remote debugging sessions are preserved over
Windows PowerShell
remote sessions that are disconnected and then later reconnected.
A RunNow parameter for Register-ScheduledJob and Set-ScheduledJob eliminates the need to set an immediate start date and time for jobs by using the Trigger parameter.
Invoke-RestMethod and Invoke-WebRequest now let you set all headers by using the Headers parameter. Although this parameter has always existed, it was one of several parameters for the web cmdlets that resulted in exceptions or errors.
Get-Module has a new parameter, FullyQualifiedName, of the type ModuleSpecification[]. The Name parameter of Get-Module now lets you specify a module by using the module's name, version, and
GUI
D. As before, it also lets you specify a module by using only the name.
The default execution policy setting on
Windows Server
2012 R2 Preview is RemoteSigned. On
Windows 8
.1 Preview, there is no change in default setting.
Starting in
Windows PowerShell
4.0, method invocation by using dynamic method names is supported.
Asynchronous workflow jobs are no longer deleted when the time-out period that is specified by the PSElapsedTimeoutSec workflow common parameter has elapsed.
A new parameter, RepeatIndefinitely, has been added to the New-JobTrigger and Set-JobTrigger cmdlets. This eliminates the necessity of specifying a TimeSpan.MaxValue value for the RepetitionDuration parameter to run a scheduled job repeatedly, for an indefinite period.
A Passthru parameter has been added to the Enable-JobTrigger and Disable-JobTrigger cmdlets. The Passthru parameter displays any objects that are created or modified by your command.
The parameter names for specifying a workgroup in the Add-Computer and Remove-Computer cmdlets are now consistent. Both cmdlets now use the parameter WorkgroupName.
A new common parameter,
Pipeline
Variable
, has been added.
Pipeline
Variable
lets you save the results of a piped command (or part of a piped command) as a variable that can be passed through the remainder of the pipeline.
Windows PowerShell
now lets you add new keywords.
Collection filtering by using a method syntax is now supported.
The Get-Process cmdlet has a new switch parameter, IncludeUserName.
A new cmdlet, Get-File
Hash
, that gets information about file hashes, has been added.
In
Windows PowerShell
4.0, if a module uses the DefaultCommandPrefix key in ist manifest, or if the user imports a module with the Prefix parameter, the ExportedCommands property of the module shows the commands in the module with the prefix. When you run the commands by using the module-qualified syntax, ModuleName\CommandName, the command names must include the prefix.
The value of $PSVersionTable.PSVersion has been updated to 4.0.
