**Example 1: To disassociate one or more instances from an event window** The following ``disassociate-instance-event-window`` example disassociates one or more instances from an event window. Specify the ``instance-event-window-id`` parameter to specify the event window. To disassociate instances, specify the ``association-target`` parameter, and for the parameter values, specify one or more instance IDs. :: aws ec2 disassociate-instance-event-window \ --region us-east-1 \ --instance-event-window-id iew-0abcdef1234567890 \ --association-target "InstanceIds=i-1234567890abcdef0,i-0598c7d356eba48d7" Output:: { "InstanceEventWindow": { "InstanceEventWindowId": "iew-0abcdef1234567890", "Name": "myEventWindowName", "CronExpression": "* 21-23 * * 2,3", "AssociationTarget": { "InstanceIds": [], "Tags": [], "DedicatedHostIds": [] }, "State": "creating" } } For event window constraints, see `Considerations <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/event-windows.html#event-windows-considerations>`__ in the Scheduled Events section of the *Amazon EC2 User Guide*. **Example 2: To disassociate instance tags from an event window** The following ``disassociate-instance-event-window`` example disassociates instance tags from an event window. Specify the ``instance-event-window-id`` parameter to specify the event window. To disassociate instance tags, specify the ``association-target`` parameter, and for the parameter values, specify one or more tags. :: aws ec2 disassociate-instance-event-window \ --region us-east-1 \ --instance-event-window-id iew-0abcdef1234567890 \ --association-target "InstanceTags=[{Key=k2,Value=v2},{Key=k1,Value=v1}]" Output:: { "InstanceEventWindow": { "InstanceEventWindowId": "iew-0abcdef1234567890", "Name": "myEventWindowName", "CronExpression": "* 21-23 * * 2,3", "AssociationTarget": { "InstanceIds": [], "Tags": [], "DedicatedHostIds": [] }, "State": "creating" } } For event window constraints, see `Considerations <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/event-windows.html#event-windows-considerations>`__ in the Scheduled Events section of the *Amazon EC2 User Guide*. **Example 3: To disassociate a Dedicated Host from an event window** The following ``disassociate-instance-event-window`` example disassociates a Dedicated Host from an event window. Specify the ``instance-event-window-id`` parameter to specify the event window. To disassociate a Dedicated Host, specify the ``association-target`` parameter, and for the parameter values, specify one or more Dedicated Host IDs. :: aws ec2 disassociate-instance-event-window \ --region us-east-1 \ --instance-event-window-id iew-0abcdef1234567890 \ --association-target DedicatedHostIds=h-029fa35a02b99801d Output:: { "InstanceEventWindow": { "InstanceEventWindowId": "iew-0abcdef1234567890", "Name": "myEventWindowName", "CronExpression": "* 21-23 * * 2,3", "AssociationTarget": { "InstanceIds": [], "Tags": [], "DedicatedHostIds": [] }, "State": "creating" } } For event window constraints, see `Considerations <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/event-windows.html#event-windows-considerations>`__ in the Scheduled Events section of the *Amazon EC2 User Guide*.
