This ensures that customers can obtain the necessary language packs to support their preferred language or multilingual interface configuration.

In scenarios where enterprise customers have client machines directly connected to public Windows Update servers, administrators may opt to prevent the deployment of the .NET Framework 4.8.1 to these machines.
