How to install help for Windows PowerShell? I am getting the "Get-Help cannot find the Help files for this cmdlet on this computer" error.

By default, help files are not installed for Windows PowerShell. So if you run the help command, you will get the syntax-only help and the "Get-Help cannot find the Help files for this cmdlet on this computer".

For example:

PS C:\Users\fyicenter> help get-date

NAME
    Get-Date

SYNTAX
    Get-Date [[-Date] <datetime>] [-Year <int>] [-Month <int>] ...

ALIASES
    None

REMARKS
    Get-Help cannot find the Help files for this cmdlet on this computer. 
    It is displaying only partial help.
        -- To download and install Help files for the module that includes 
           this cmdlet, use Update-Help.
        -- To view the Help topic for this cmdlet online, type: "Get-Help 
           Get-Date -Online" or go to http://go.microsoft.com/fwlink/?LinkID=113313.

To install the help information, you need to run the "Update-Help" command in Windows PowerShell as an administrator:

1. Type "Windows PowerShell" in the Windows search box.

2. Right-click on "Windows PowerShell" in the search match list and select "Run as administrator" from the context menu.

3. Run the "Update-Help" command at the Windows PowerShell prompt. It will download and install help information from Microsoft server one module at a time.

PS C:\Users\fyicenter> update-help

Updating Help for module DirectAccessCli
   Locating Help Content...
...

After the installation is done, the "help" command will return full help information. For example:

PS C:\Users\fyicenter> help get-date

NAME
    Get-Date

SYNOPSIS
    Gets the current date and time.


SYNTAX
    Get-Date [[-Date] <datetime>] [-Year <int>] [-Month <int>] ...

DESCRIPTION
    The Get-Date cmdlet gets a DateTime object that represents the 
    current date or a date that you specify. It can
    format the date and time in several Windows and UNIX formats. 
    You can use Get-Date to generate a date or time
    character string, and then send the string to other cmdlets or 
    programs.
