Certain PowerShell commands not returning anything

[dam.beaver]

So to begin with I only know some basics about coding but I want to learn more. In this case I found PowerShell interesting. I went to PowerShell to poke around, and tried the help command. Help files are not installed. Stupidest thing I've ever heard about a terminal. Update-help starts the process, but then it spits an error saying it couldn't retrieve the HelpInfoXml file. I can't even begin to figure out how to get that on there or if it would've come with the pc if I hadn't reinstalled windows for a new drive.

 

Second but not that important thing is I tried this command "Invoke-WebRequest -Uri (Get-Module <ModuleName>).HelpInfoUri -OutFile helpinfo.xml" and it said that the argument (it's "arg" right?) was null or empty. How do I make an argument? 

 

Lastly some commands like Get-Module HelpInfoXml or Select-Object HelpInfoUri wont return anything.
