  1. Open SQL Configuration Manager
  2. Services > Sql Service Instance > Properties > Startup Parameters
  3. Add the following statement: -T1222
  4. Confirm the change by navigating to Advanced > Startup Parameters. This should be grayed out and display the new value that was added at the end with a delimited semicolon.
