Question

I need to enable two Windows Features using Powershell. But I don’t know their names or how to find them.

So far I have managed to install the IIS and stop the Default Application Pool using a script found here.

function InstallFeature($name) {
    cmd /c "ocsetup $name /passive"
}
InstallFeature IIS-WebServerRole
    InstallFeature IIS-WebServer
        InstallFeature IIS-CommonHttpFeatures
            InstallFeature IIS-DefaultDocument
            InstallFeature IIS-DirectoryBrowsing
            InstallFeature IIS-HttpErrors
            InstallFeature IIS-HttpRedirect
            InstallFeature IIS-StaticContent
        InstallFeature IIS-HealthAndDiagnostics
            InstallFeature IIS-CustomLogging
            InstallFeature IIS-HttpLogging
            InstallFeature IIS-HttpTracing
            InstallFeature IIS-LoggingLibraries
        InstallFeature IIS-Security
            InstallFeature IIS-RequestFiltering
            InstallFeature IIS-WindowsAuthentication
        InstallFeature IIS-ApplicationDevelopment
            InstallFeature IIS-NetFxExtensibility
            InstallFeature IIS-ISAPIExtensions
            InstallFeature IIS-ISAPIFilter
            InstallFeature IIS-ASPNET
    InstallFeature IIS-WebServerManagementTools 
        InstallFeature IIS-ManagementConsole 
        InstallFeature IIS-ManagementScriptingTools

Answer 1

if you are in windows 2008R2 there is a module for this :

Import-Module servermanager

this module exports 3 cmdlets : Get-WindowsFeature, Add-WindowsFeature and remove-WindowsFeature

so you can make someting like
get-windowsfeature *frame* to list the .net features and install it via command like
Add-WindowsFeature Net-Framework
