Ive heard a lot about Windows PowerShell lately. Do I need to know PowerShell to get the most out of R2?
Not necessarily, but it helps. One thing that’s clear with Windows Server 2008 R2 is that Microsoft is very high on PowerShell, so admins who understand it will most certainly be able to get the most out of R2 and other Microsoft technologies going forward. Case in point: Windows Server 2008 R2 includes more than 240 brand new PowerShell cmdlets, with notable enhancements for Active Directory and Group Policy. That’s not to say the GUI is going anywhere. Still, while you can do pretty much everything through PowerShell that you can with the GUI, the OS has a lot more to offer from the command line than you can get otherwise.
