If you think you may want to use the workflow again later, but you don’t want users with Design or Full Control permission to be able to associate it to a list or library, you can deactivate the workflow solution as a feature in the site collection. Deactivating the workflow site feature will terminate any running instances of the workflow and the workflow cannot be associated to a list or library.
You must be a Site Collection Administrator to perform these procedures.
|1.||Delete the workflow’s association to all lists and libraries. See Removing a Workflow Association for details on how to do that. ||
|2.||In the top level site of the site collection, go to Site Actions > Site Settings.|
|3.||In the Site Collection Administration section, click Site collection features.|
|4.||Locate the workflow in the feature list and click Deactivate.|
|5.||Click Deactivate this feature to confirm the action.|
