Microsoft PowerShell 2.0 preview released

Posted on Tuesday, Nov 06 2007 @ 20:36 CET by Thomas De Maesschalck
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 release.

  • 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 them.

  • 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.
