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.

  • Please add 3 and 2 and type the answer here:
  • Post
  • Right now, like, at the time I put this in, I can't get ANY download link to work without it throwing an exception or returning 404. Me thinks your download servers are dead.

  • I'd just commented that the download site wasn't working when it finally came up.

    Only it ONLY works in XP SP2. This is unfortunate as my company's standard is only SP1. So I can't use it.
  • After installing, I don't see it listed in Add or Remove Programs.  Is there any way to uninstall it?
  • Why is System.Management.Automation.dll missing from RC2?

  • Andrew:  RC2 installs as an update to Windows.  You need to select the "Show Updates" box in order to manage it.

    Alex: The DLL exists, but it is added to the Global Assembly Cache (GAC) of the machine.  You should see it in the Visual Studio dialog that lets you pick DLLs from the GAC.  If you are compiling something against it from the cmdine, I'm fond of the trick:  


  • Direct connection to ADSI objects works well BUT...

    There is no indication of how to return a collection of objects from within a container.

    I can grab the container (OU or otherwise) but haven't seen how to get the objects it contains.

    How about a hint.
  • I see System.Management.Automation in the GAC but it does not show up in VS 2005's Add Reference dialog.

    Should I uninstall and install again? Anyone else seeing this?


  • Thanks. Some people in Ukraine and Russia also read your blog and are interesting in Windows PowerShell. For those we translate such articles and publicate these in our blog:
  • A working installer for Vista RC1 would be greatly appreciated.
  • Is it possible to use winxp or 2k3 versions for Vista? (i will have Vista only for 2 weeks, so i think i dont have time to wait Vista package;))
  • Has anyone installed this on a Windows Server 2003 Enterprise which had RC1 that was uninstalled through Add/Remove Programs per install instructions? All of my system end up with a dialog: An error in updating your system has occurred. Select 'OK' to undo the changes that have been made. This is with: WindowsServer2003-KB923567-x86-ENU.exe
  • Any idea when the Vista installer is likely to become available?
  • What happend to Make-Shell? Was this functionality removed or is there a differenet procedure?
  • Craig;

    Make-Shell.exe will be released as part of our SDK.  That said, most people will want to develop snapins to add custom functionality, rather than make their own shell.

  • Nick;

    "As fast as we can" is the best answer I have right now.  As I mentioned above, the technology we are using for the Vista setup package is itself undergoing change, preventing us from making a setup package right now.
