Disabling Remote Registry Service
If the Remote Registry Service is disabled without proper preparation, it may disrupt legitimate administrative tasks that require remote access to the registry, leading to potential delays in troubleshooting and system management.

explanation for non-techies**

Microsoft is introducing new recommendations for Microsoft Defender for Endpoint, a security tool used to protect computers and networks. Think of Microsoft Defender for Endpoint as a security guard for your computer systems, constantly on the lookout for potential threats. Microsoft Secure Score is like a report card that tells you how well your security measures are performing and what you can do to improve them.

Starting from late November to mid-December 2025, Microsoft will roll out new suggestions to help organizations enhance their security. One of these suggestions is to disable the Remote Registry Service on Windows. This service is like a door that allows changes to be made to your computer's settings from a distance. By disabling it, you reduce the risk of someone making unauthorized changes.

These updates are specifically for customers who have Microsoft 365 E5 or Microsoft Defender for Endpoint Plan 2. If you're managing these systems, you'll see new recommendations in your Secure Score dashboard. It's like getting new tips on how to improve your security report card.

To prepare, you'll want to review these new recommendations when they become available and take the necessary actions to implement them. It's also important to communicate these changes to your security and endpoint management teams so everyone is on the same page.

No compliance issues have been identified with these changes, but it's always a good idea to review them to ensure they fit your organization's needs. You can learn more about these updates and how to implement them by visiting Microsoft's official documentation online.
