Disabling non-default services

We don't recommend applying policies that disable services that aren't by default by Microsoft.

There are a few reasons why we recommend against disabling non-default services:

A service your admins installed after the initial setup is usually one that you need but wasn't in the original deployment. In these cases, you should tell your admins not to install the service in the first place as opposed to only disabling it after it's installed.

Blocking the Windows version of a service doesn't stop admins or non-admins from installing third-party equivalents that pose higher security risks.

Establishing a baseline that disables non-default Windows services, such as the World Wide Web Publishing Service (W2SVC) or Internet Information Services (IIS), may give auditors the impression that they're inherently insecure and should never be used.

If the service is never installed, disabling it adds unnecessary work to establishing the baseline and verification for your system.

How to read this guide

This article describes each service one by one, using the following variables.

The service name is the internal name of the service.

The description describes what each service is.

Installation describes which OS the service exists on.

If the service is always installed , it's available on both Windows Server 2016 Core and Windows Server 2016 with Desktop Experience.

If the service is only with Desktop Experience , it isn't available on Windows Server 2016 Core.

The startup type is how Windows determines when and how the service is started.

Recommendation lists Microsoft's recommended configuration for this service on a typical Windows Server 2016 deployment in an enterprise that's not using the server as an end-user desktop replacement.

Do not disable means you should never disable this service.

OK to disable means you can disable this service if you don't need it.

Already disabled means Windows disabled this service by default.

Should be disabled means you should always disable this service to increase security.

The comments show extra explanations and notes if you need more context.
