This article describes the Microsoft support policy about disabling built-in Windows services and features that are enabled by default.
We do not recommend that users disable built-in Windows services or features. These built-in services and features are highly optimized, they use less memory, and most are combined in order to use fewer running processes. Disabling these services and features won’t help your computer's performance or security concerns and may have unintended consequences.
Therefore, Microsoft may request that you re-enable built-in Windows services and features during best-effort support that we provide while troubleshooting user issues. We recommend that users maintain the Windows default settings wherever possible or otherwise apply industry-standard configurations such as the Microsoft Windows security guidance.
Microsoft has thoroughly tested this guidance in our application compatibility laboratories, and we are confident that it is appropriate for any organization that wants to help secure its Windows-based computers. To download the security baseline settings that comply with this guidance, go to the following Microsoft websites:
