 ### Local administrators collection (using SAM-R queries) feature will be disabled
 The remote collection of local administrators group members from endpoints using SAM-R queries in Microsoft Defender for Identity will be disabled by mid-May 2025. This data is currently used to build potential lateral movement path maps, which will no longer be updated after this change. An alternative method is being explored. The change will occur automatically by the specified date, and no administrative action is required.
