PowerShell v3 comes without help files. To get help, you need to download the help files first. In an elevated PowerShell console, use this command:
PS> Update-Help -Force
Currently, help is available only on English systems. To use English help on non-English systems, download help like this:
PS> Update-Help -UICulture en-us -Force
Then, go to the downloaded help files and copy them from the en-US folder to your locale folder:
PS> explorer $pshome
