Problem As of July 2025, 26 of 145 tenant settings are in Preview-and 12 ship Enabled by default. Preview featuresfall outside Microsoft’s normal SLA, support and data-residency guarantees . Some previews are already scheduled for retirement yet still activate automatically, exposing organisations to dead-end features. Admins have no master switch for turning off default features. So they must re-audit the portal after every monthly release. This is a gap called out repeatedly in the community community.fabric.microsoft.com. Impact Production workloads lose contractual SLAs the moment they touch an auto-enabled preview. Compliance and data-sovereignty promises can be broken without any conscious action by the customer. Security posture erodes: new, unvalidated endpoints light up before risk teams can review them. Admin overhead skyrockets; scarce BI teams spend time chasing settings drift instead of delivering value. Proposal Ship every preview feature with Default = OFF for all tenants and capacities. Expose a single “Enable Previews” master toggle so early adopters can opt-in deliberately. Push an Admin Center notification each time a new preview becomes available or an existing one flips GA/Retired. Benefits Preserves Microsoft’s valuable innovation pipeline while respecting enterprise governance. Eliminates accidental loss of SLA, support and compliance for mission-critical solutions. Saves administrators countless audit hours and reduces avoidable help-desk tickets. Builds customer trust. Admins remain in full control of when experimental code enters production. Ask Vote to set Previews = OFF by default and add a master opt-in switch. The change is minimal for Microsoft but delivers maximum risk reduction for every customer running Power BI and Fabric in production.
