If you upgraded your ConfigMgr 1702 or earlier environment to Configmgr 1706 and in the status messages after the upgrade you get :
Microsoft SQL Server reported SQL message 2627, severity 14: [Microsoft][SQL Server Native Client 11.0][SQL Server]Violation of PRIMARY KEY constraint ‘SUM_DriverUpdates_PK’. Cannot insert duplicate key in object ‘dbo.SUM_DriverUpdates’. The duplicate key value is (d8483f4f-0390-49db-b251-faf884dd8eaf
Be aware that the Product Group are aware of this issue and are on a working on a fix. The result of this problem is that admins cannot see new Surface driver updates.
Other than that, nothing else is impacted so it can be ignored.
Hope it helps ,
