DESCRIPTION<br />
The Get-Help cmdlet displays information about <strong>Windows</strong> <strong>PowerShell</strong> concepts and<br />
<strong>com</strong>mands, including cmdlets, providers, functions, aliases and scripts.<br />
Get-Help gets the help content that it displays from help files on your<br />
<strong>com</strong>puter. Without the help files, Get-Help displays only basic information<br />
about <strong>com</strong>mands. Some <strong>Windows</strong> <strong>PowerShell</strong> modules <strong>com</strong>e with help files. However,<br />
beginning in <strong>Windows</strong> <strong>PowerShell</strong> <strong>3.0</strong>, the modules that <strong>com</strong>e with <strong>Windows</strong><br />
<strong>PowerShell</strong> do not include help files. To download or update the help files for<br />
a module in <strong>Windows</strong> <strong>PowerShell</strong> <strong>3.0</strong>, use the Update-Help cmdlet. You can also<br />
view the help topics for <strong>Windows</strong> <strong>PowerShell</strong> online in the TechNet Library at http:<br />
//go.microsoft.<strong>com</strong>/fwlink/?LinkID=107116<br />
To get help for a <strong>Windows</strong> <strong>PowerShell</strong> <strong>com</strong>mand, type "Get-Help" followed <strong>by</strong> the<br />
<strong>com</strong>mand name. To get a list of all help topics on your system, type "Get-Help<br />
*".<br />
Conceptual help topics in <strong>Windows</strong> <strong>PowerShell</strong> begin with "about_", such as<br />
"about_Comparison_Operators". To see all "about_" topics, type "Get-Help<br />
about_*". To see a particular topic, type "Get-Help about_", such<br />
as "Get-Help about_Comparison_Operators".<br />
