175 C H A P T E R 1 0 Windows PowerShell W indows PowerShell has become the de facto platform for automating the administration of Windows-based environments. Built on top of the common language runtime (CLR) and the Microsoft .NET Framework, Windows PowerShell has brought a whole new paradigm for configuring and managing Windows servers in enterprise environments. Windows Server 2012 R2 introduces the latest iteration of the platform, Windows PowerShell 4.0, and it has some exciting new capabilities we’ll look at. But first let’s begin by briefly reviewing what was introduced in Windows PowerShell 3.0 in Windows Server 2012. Previous enhancements in Windows PowerShell 3.0 Windows PowerShell 3.0 in Windows Server 2012 previously introduced numerous new capabilities that helped bring added flexibility and power for managing cloud and multiserver environments to the platform. Some of the key enhancements that were added to Windows PowerShell 3.0 included the following: New architecture Windows PowerShell 3.0 was built upon the Windows Management Framework 3.0, which introduced a new Windows Management Instrumentation (WMI) provider model that reduces dependency on COM, a new application programming interface (API) for performing standard Common Information Model (CIM) operations, and the capability of writing new Windows PowerShell cmdlets in native code. Windows Management Framework 3.0 also introduced improvements that made WinRM connections more robust to support long-running tasks and be more resilient against transient network failure. Disconnected sessions Windows PowerShell 3.0 introduced persistent user-managed sessions (PSSessions) that are not dependent upon the session in which they were created. By using the New-PSSession cmdlet, you can create and save a session on a remote server and then disconnect from the session. The Windows PowerShell commands in the session on the remote server will then continue to execute, even though you are no longer connected to the session. If desired, you can reconnect later to the session from the same or a different computer.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
