To install PowerShell on Windows Server 2008 R2 or Hyper-V Server 2008 R2, following features needs to be installed.

1. NetFx2-ServerCore
2. NetFx3-ServerCore
3. MicrosoftWindowsPowerShell

Because Powershell is built on DotNet framework, DotNet 2.0 and 3.5  has to be installed prior to PowerShell installation.

To install PowerShell from command line, run following from elevated command prompt

DISM.exe /online /enable-feature /featurename:NetFx2-ServerCore DISM.exe /online /enable-feature /featurename:NetFx3-ServerCore DISM.exe /online /enable-feature /featurename:MicrosoftWindowsPowerShell

Or run following command if it’s an 64bit machine

DISM.exe /online /enable-feature /featurename:NetFx2-ServerCore-WOW64 
DISM.exe /online /enable-feature /featurename:NetFx3-ServerCore-WOW64 
DISM.exe /online /enable-feature /featurename:MicrosoftWindowsPowerShell-WOW64 

To enable DotNet 3.5 from command line, run following from elevated command prompt

dism.exe /online /enable-feature /featurename:NetFx3

This useful command lets you wait for signals from other command windows or even across the network.

waitfor.exe is in windows\system32 directory.

The simple case for the tool is in one command window you do a “waitfor foobar” and it’ll block until in another window you do a “waitfor /SI foobar”.

powercfg.exe is a windows built in tool to config power management. powercfg.exe is a command line utility, it’s easy to integrate powercfg.exe into scripts.
