# Setting up Maintenance Windows
<a name="setting-up-maintenance-windows"></a>

Before users in your AWS account can create and schedule maintenance window tasks using Maintenance Windows, a tool in AWS Systems Manager, they must be granted the necessary permissions. In addition, you must create an IAM service role for maintenance windows and the IAM policy to attach to it.

**Before you begin**  
In addition to the permissions you configure in this section, the IAM Entities (users, roles, or groups that will work with maintenance windows should already have general maintenance window permissions. You can grant these permissions by assigning the IAM policy `AmazonSSMFullAccess` to the Entities, or assigning a custom IAM policy that provides a smaller set of access permissions for Systems Manager that covers maintenance window tasks.
