A standalone PowerShell script to assess this control automatically. Review before running it in your environment.

$iisFeature = Get-CimInstance -ClassName Win32_OptionalFeature -Filter "Name='IIS-WebServerRole'"
$iisHostableWebCoreFeature = Get-CimInstance -ClassName Win32_OptionalFeature -Filter "Name='IIS-HostableWebCore'"
if (-not $iisFeature -or $iisFeature.InstallState -ne 2 -and -not $iisHostableWebCoreFeature -or $iisHostableWebCoreFeature.InstallState -ne 2) { Write-Output "PASS"; Exit 0 } 
Write-Output "FAIL"; Exit 1
