Microsoft Windows PowerShell is a new command-line shell and scripting language that is designed for system administration and automation. Windows PowerShell lets IT professionals and developers control and automate the administration of Windows and applications. Also, Windows PowerShell is built on the Microsoft .NET Framework.
Windows PowerShell includes the following features:
- More than 130 command-line tools ("cmdlets") that you can use to perform common system administration tasks. These tasks include managing services, managing processes, managing event logs, managing certificates, modifying the registry, and using Windows Management Instrumentation (WMI).
- Command-line tools that are easy to learn and easy to use. These tools have standard naming conventions and common parameters. The tools also include simple tools to sort, to filter, and to format data and objects.
- Support for existing scripting languages, for existing command-line tools, and for multiple versions of Windows. These versions include Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008.
- Features that let users browse data stores as if they were file systems. These data stores include the registry and certificate stores.
- Standard utilities for managing Windows data in different stores and formats. These stores and formats include Active Directory Service Interfaces (ADSI), Windows Management Instrumentation (WMI), COM objects, ActiveX Data Objects (ADO), HTML, and XML.
- Sophisticated expression parsing and manipulation of objects in the .NET Framework at the command line. This manipulation includes the pipelining of objects to help IT professionals work more efficiently and effectively.
- An extensible interface that enables independent software vendors and enterprise developers to build custom cmdlets. You can use custom cmdlets to meet unique application and system administration requirements.

Windows PowerShell 1.0 uses Package Installer technology for Windows XP-based and for Windows Server 2003-based installations. The location of the Windows PowerShell installation folder is not configurable.
On 32-bit versions of Windows, Windows PowerShell 1.0 is installed in the following folder:
%windir%\System32\WindowsPowerShell\V1.0
Note In this folder, %windir% represents the Windows system folder. Typically, this folder is C:\Windows.
By default, both the 32-bit versions and 64-bit versions of Windows PowerShell are installed in the following locations on 64-bit versions of Windows:

Restart requirements
You do not have to restart the computer after you install Windows PowerShell.
A restart is required only when files that you are installing or uninstalling are also being used by another program. This scenario occurs only when the same version of Windows PowerShell is installed. If these files are being used, a restart prompt appears unless the installer is running in unattended mode.
Uninstall Windows PowerShell
You cannot install Windows PowerShell 1.0 if it is already installed. To determine whether Windows PowerShell 1.0 is installed, locate the
Installregistry entry in the following registry path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Powershell\1\Install
If the value of the
Install entry is 1, Windows PowerShell 1.0 is installed. If the
Install entry is not present, Windows PowerShell 1.0 is not installed.
If you install Windows PowerShell 1.0 on Windows Server 2003 with Service Pack 1, and then upgrade to Windows Server 2003 with Service Pack 2, you cannot uninstall Windows PowerShell 1.0. Because Windows PowerShell is packaged as a Windows update, uninstalling Windows PowerShell after you apply a service pack is considered uninstalling out of the prescribed order.
