Final answer:
To reopen a completed Guided Setup task, try clicking the 'Mark as Incomplete' button if available, or submit a helpdesk request, and as a last resort, restart the Guided Setup entirely.
Step-by-step explanation:
When working with a Guided Setup task on a platform, typically if a task is marked as complete but needs to be readdressed, you may have a few options depending on system capabilities. However, for many systems, once a task is marked as complete, it cannot be reopened (closed tasks cannot be reopened). If the system does allow reopening a completed task, the correct option would usually be to click the Mark as Incomplete button, and this would reset the status of the task allowing you to make the necessary changes or updates. If there is no direct way to mark a task as incomplete, then submitting a request in a helpdesk interface like HI could be a recourse. Lastly, restarting the Guided Setup entirely is a more drastic measure that should only be considered if there are no other ways to reopen an individual task.
