• From the list of results select Credential Manager
• From this screen, you can manage Web Credentials and
  Windows Credentials.

Tasks still show in Task Scheduler despite being deleted

The OP has not mentioned deleting any program files.

Hi John,

The username and password credentials you have entered in task scheduler are stored in the system cache files. For us to resolve your concern and delete the list of accounts or usernames that you no longer have on your computer, we suggest that you follow
the steps on this link to run a disk cleanup that will delete the system cache files.

We look forward to your response once you complete the steps.
