Microsoft has released a technology preview version of PowerShell 2.0. This program is a command line interface shell and scripting language for Windows.
This software is a pre-release version. It will not work the way a
final version of the software does. Features will change before final
The goal of this CTP release is to provide a preview to the community on
early thinking and direction on key 2.0 features and get early feedback on
Windows PowerShell 2.0 CTP release is compatible with and replaces Windows
PowerShell 1.0. You must un-install PowerShell 1.0 to install the PowerShell
2.0 CTP release.
Windows PowerShell 2.0 CTP release will continue to use the execution
policy setting of PowerShell 1.0, if present. PowerShell 1.0 installer does
not remove or change the execution policy on un-installation.
PowerShell 2.0 Remoting features will not work correctly on Windows Vista
RTM. Please install Windows Vista Service Pack 1 (SP1) Beta to enable
PowerShell Remoting features.
When Windows PowerShell 2.0 CTP is launched with an execution policy of
“Restricted,” it will display an error message while loading the types
and formatting files. To prevent this error message, change the execution
policy to one that enables PowerShell’s scripting features – such as
RemoteSigned. For more information about PowerShell’s execution policies,
type “Get-Help about_signing”.
Graphical PowerShell is a very early alpha version meant for previewing
early thinking and getting feedback.
PsJobs rely on the remoting features of Windows PowerShell 2.0. To use
PsJobs, remoting must be enabled on Windows PowerShell, even if the PsJob
runs only on the local computer.
