In PowerShell 5.1 one can get help about the 'PowerShell Help System' in general with Get-Help. However, in PowerShell 6.0Beta1 this is broken (on Windows)

Steps to reproduce

Get-Help

Expected behavior

TOPIC
Windows PowerShell Help System

SHORT DESCRIPTION
Displays help about Windows PowerShell cmdlets and concepts.

LONG DESCRIPTION
Windows PowerShell Help describes Windows PowerShell cmdlets,
functions, scripts, and modules, and explains concepts, including
the elements of the Windows PowerShell language.

Windows PowerShell does not include help files, but you can read the
help topics online, or use the Update-Help cmdlet to download help files
to your computer and then use the Get-Help cmdlet to display the help
topics at the command line.

You can also use the Update-Help cmdlet to download updated help files
as they are released so that your local help content is never obsolete.

Without help files, Get-Help displays auto-generated help for cmdlets,
functions, and scripts.

ONLINE HELP
You can find help for Windows PowerShell online in the TechNet Library
beginning at http://go.microsoft.com/fwlink/?LinkID=108518.

To open online help for any cmdlet or function, type:

    Get-Help <cmdlet-name> -Online

UPDATE-HELP
To download and install help files on your computer:

   1. Start Windows PowerShell with the "Run as administrator" option.
   2. Type:

      Update-Help

After the help files are installed, you can use the Get-Help cmdlet to
display the help topics. You can also use the Update-Help cmdlet to
download updated help files so that your local help files are always
up-to-date.

For more information about the Update-Help cmdlet, type:

   Get-Help Update-Help -Online

or go to: http://go.microsoft.com/fwlink/?LinkID=210614

GET-HELP
The Get-Help cmdlet displays help at the command line from content in
help files on your computer. Without help files, Get-Help displays basic
help about cmdlets and functions. You can also use Get-Help to display
online help for cmdlets and functions.

To get help for a cmdlet, type:

    Get-Help <cmdlet-name>

To get online help, type:

    Get-Help <cmdlet-name> -Online

The titles of conceptual topics begin with "About_".
To get help for a concept or language element, type:

    Get-Help About_<topic-name>

To search for a word or phrase in all help files, type:

    Get-Help <search-term>

For more information about the Get-Help cmdlet, type:

    Get-Help Get-Help -Online

or go to: http://go.microsoft.com/fwlink/?LinkID=113316
