Over the past few years, Microsoft has been quietly building a next-generation administrative shell product codenamed Monad. Now launched with the more formal name PowerShell, this product is in late beta, and a release candidate was delivered at the MMC Summit in April. PowerShell will ship as part of both Exchange 2007 and MOM 3 (now renamed System Center Operations Manager 2007), and in the WinFX SDK towards the end of this year. You can get PowerShell RC1 for 32- and 64-bit CPUs from the Microsoft website, which requires a mandatory registration using Passport. Pick up the documentation pack too. To run PowerShell, you first need to install .NET Framework 2, which you can also download www.reskit.net.
