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

I have a batch script which remove a folder and re-create it. The command that remove a folder is rd /s/q and the command create folder is mkdir. Recently I see something weird happening, everytime when the folder is deleted and re-created, there is error message Access is denied displayed. However, if I rerun the create folder command laer, it always pass successfully.

The explanation on http://support.microsoft.com/?id=159199 seems make sense,

This file is in a state known as pending deletion. This file has been deleted, but there are still handles open to it. NTFS will wait until all handles to this file are closed before updating the index. If an attempt is made to access the file, however, NTFS will deny the attempt. Because the file is listed in the index, but is effectively deleted, you can see the file but you cannot access it.

The workaround here is add a 60 seconds sleep between the folder deletion and folder creation operation.

Getting the current working directory
cd /d %~dp0
Comment: %0 is the name of the batch file. ~dp gives you the drive and path.
