Version 2 provides a snap-in registered to the machine and a module that can be installed by a user without administrative privileges. The module is installed to a user profile but can also be installed to a secure machine location for use by all users. The snap-in and the module provide the same set of cmdlets, but the module does provide additional functions and aliases for backward call-compatibility with version 1 cmdlets.

To use either the module or the snap-in from from this release, you must install PowerShell 2.0. PowerShell 2.0 is included in both Windows 7 by default, and Windows Server 2008 R2 as an optional feature.

See the help section for instructions for use and the list of features.
