If you do not need a preset tag, you can delete it.
Background information
When you add a preset tag to a resource, a custom tag that resides in the same region as the resource is actually added to the resource. When you delete the preset tag, you delete only the preset tag itself. The custom tag that is added to the resource is not deleted.
Procedure
Log on to the Resource Management console.
In the left-side navigation pane, choose .
On the Predefined Tags page, find the preset tag that you want to delete and click Delete in the Actions column.
In the Delete Tag dialog box, click Delete.
