Since the release of Windows 7 and Windows Server 2008 R2, Windows PowerShell is included in the operating system and enabled by default. This means Windows PowerShell 3.0 will be available in the next version of Windows.
A preview version for developers of the next Windows version was released a few weeks ago, which means we also got a preview of Windows PowerShell 3.0. The preview version of the client operating system is available here, while the server version is available on MSDN.
Earlier this week the PowerShell team announced that a Community Technology Preview (CTP 1) is available for download, which means we can also try out PowerShell 3.0 on computers running Windows 7 and Windows Server 2008 R2. The current version of the Windows Management Framework includes Windows PowerShell 2.0, Windows Remote Management (WinRM) 2.0 and Background Intelligent Transfer Service (BITS) 4.0, while the new Windows Management Framework CTP contains Windows PowerShell 3.0, Windows Management Instrumentation (WMI) and Windows Remote Management.
Some of the most important new features in PowerShell 3.0 is listed in the previous mentioned announcement from the PowerShell team, but there is also a huge number of other new features.
A great number of persons in the PowerShell community has already started to discover and write about the new features. One of them is the new Windows PowerShell Web Access in the next version of Windows Server, which I
ve previously written an article about.
Instead of listing all the articles Ive discovered so far in this article, I posted them as a TechNet Wiki article as part of the existing PowerShell V3 Guide:
I would like to encourage you to contribute to the TechNet Wiki article when you discover new writings about Windows PowerShell 3.0.
