I am writing a PowerShell script to host a website in IIS.

I tried this script in a machine where there is no IIS installed and I got error so I want to check if IIS is installed and then I want to host a website in ISS.

Below is the script I am trying but it is not working:

$vm = "localhost";
$iis = Get-WmiObject Win32_Service -ComputerName $vm -Filter "name='IISADMIN'"

if ($iis.State -eq "Running") {
    Write-Host "IIS is running on $vm"
} 
else {
    Write-Host "IIS is not running on $vm"
}

Please help me with any PowerShell script to check if IIS is installed or not.

if ((Get-WindowsFeature Web-Server).InstallState -eq "Installed") {
    Write-Host "IIS is installed on $vm"
} 
else {
    Write-Host "IIS is not installed on $vm"
}
