With Windows 10 and Windows Server 2016, a new and simplified IISAdministration module was released side by side with the existing WebAdministration Cmdlets. The new module contains simple cmdlets and provide direct access to the server manager. It also offers better support for pipeline and scaling. 

Though you can manage IIS with the IIS Manager GUI, using PowerShell gives you much more control, is much more convenient and can be easily automated. Here's a brief overview of the basic IIS management with PowerShell.  

Create a directory for your site. I will name my site 'CityOverflow'.
New-Item -ItemType Directory -Name 'CityOverflow' -Path 'C:\Sites'
Create the index.html that will be served when you go to your site
New-Item -ItemType File -Name 'index.html' -Path 'C:\Sites\CityOverflow'
Add some html content to your landing page. 
Add-Content -Path 'C:\Sites\CityOverflow\index.html' -Value "<h1>Hello World</h1>"
So far, we haven't used any IIS-specific features. We have just created a directory for our site that contains HTML. You can do that by using your favourite editor. I just wanted to show the basic PowerShell commands that do the same. 

Now, let's create a new IIS site that will serve our CityOverflow website. 
New-IISSite -Name 'CityOverflow' -PhysicalPath 'C:\Sites\CityOverflow\' -BindingInformation '*:8000:'
Once the IIS site is created, run Get-IISSite to get information about that site. 
Get-IISSite

Name             ID   State      Physical Path                  Bindings
----             --   -----      -------------                  --------
CityOverflow     2    Started    C:\Sites\CityOverflow\         http *:8000:
That's it. If you navigate to localhost:8000 in your browser, you will see the web page that you just created. 

To stop a running site, use the Stop-IISSite cmdlet, providing the name of the site. 
Stop-IISSite -Name "CityOverflow"

Confirm
Are you sure you want to perform this action?
Performing the operation "Stop-IISSite" on target "CityOverflow".
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"): Y
To start the site again, run Start-IISSite cmdlet.
Start-IISSite -Name "CityOverflow"
If you have more than one sites, you can start/stop all of them by piping the output of Get-IISSite to either StartIISSite or Stop-IISSite. 
Get-IISSite | Start-IISSite
To remove a site, run Remove-IISSite. 
Remove-IISSite -Name 'CityOverflow'
