Windows PowerShell RC2 Now Available

Today Microsoft announced the availability of Microsoft Windows PowerShell RC2, the command line shell and scripting language that helps IT Professionals achieve greater productivity and control of system administration. Using a new admin-focused scripting language and consistent syntax and utilities, Windows PowerShell accelerates automation.  Windows PowerShell is easy to adopt, learn, and use, because it works with existing IT infrastructure and scripting tools.


·         This Release Candidate 2 of Windows PowerShell addresses numerous customer requests based on their evaluation of Beta3 and RC1 including:

·         Direct ADSI support to allow IT Pros to more easily administer Active Directory

·         Improved support for Windows Management Instrumentation through ability to change WMI properties via methods

·         Additional logical operators (XOR and binary XOR) that make it easier to write sophisticated scripts

·         Improved help content and help functionality including new views that make it easier to find the right information.

·         Windows PowerShell 1.0 will release-to-web in Q4 CY06

·         Windows PowerShell will be leveraged by Microsoft Exchange Server 2007 and System Center Operations Manager 2007.

  • PowerShell is an incredible tool, I just wish it was available on Vista.
  • Ronald;

    It looks like you're trying to install a package that wasn't intended for distribution.  For english systems, you'll want to install the EN-Neutral package (KB number should be 925228,  You're installing KB923567 which is poorly labeled on our part (and should not be installed.)  We are working to get this incorrect link removed from the download centre.


  • Is there anyone working on a version of PowerShell that (installs/functions) under Mono? PowerShell is so awesome, I really want to use its power under multiple OS's.
  • Maybe it's just me, but it seems to me that if some new packaging software isn't complete for Powershell in Vista yet, can't you just throw together a Windows Installer package for it in about 5 minutes?  I would like to be experimenting with it in Vista, especially since Vista and Powershell are both very near a final release date.  I can't help but think it shouldn't take over two weeks to come up with a working installer for Powershell under Vista.

  • I agree.

    Heck, a batch file or just a bunch of instructions would do.

  • So its now been over 2 weeks and still no vista installer...

  • +1 on the vista installer guys.  Isn't Vista going RTM on Friday?

  • Come on, no Vista installer yet?

  • I agree with previous posters.  Vista will be on MSDN downloads within days and I really want to switch.  I'd really hate to lose access to PowerShell.

  • Are you guys still planning to release an RC2 for Vista? As I understand it the Powershell RTM is going to happen real soon now. Which version should we be waiting for?

  • System.Management.Automation.dll exits in GAC but does not show up in the Add Reference dialog Box of Visual Studio 2005. What is the solution?

  • I´m having this message "An error in updating your system has occurred" with powershell 1 and RC2, I need to install Exchange 2007 in a 2003 R2 SP2 X64. any ideas ?

  • If powershell is not supporting (installalbe) on the Vista OS how can you make the statment that powershell supports windows. If it not really ready for prim time we will move away from this new product as there are other script tool that will do the job right now.
