 #### Automatic agent lifecycle management
 The Azure File Sync agent will auto-upgrade. You can select either of two modes and specify a maintenance window in which the upgrade shall be attempted on the server. This feature is designed to help you with the agent lifecycle management by either providing a guardrail preventing your agent from expiration or allowing for a no-hassle, stay current setting.
 1. The **default setting** will attempt to prevent the agent from expiration. Within 21 days of the posted expiration date of an agent, the agent will attempt to self-upgrade. It will start an attempt to upgrade once a week within 21 days prior to expiration and in the selected maintenance window. **This option does not eliminate the need for taking regular Microsoft Update patches.**
