Well I had a lot of work to do changing service and task passwords (including boxes with a hundred or more tasks) and was not looking forward to manual process or debugging powershells. But I located
Service Credentials Manager from CJWDEV. I actually sprung for the Standard (paid) edition which I downloaded and it worked excellently.
SERVICE CREDENTIALS MANAGER
Version 2.3.0
SCMEasily track down all of the Windows services and scheduled tasks using a specific account
When it comes to changing an admin or service account password there is almost always at least one service or scheduled task that is only discovered when the service stops working after the password change, so this tool was developed to help make sure you have discovered every single one and it can also update the password on each of them remotely for you.

Free Download Buy
Free Edition
The free edition is provided in the hope that it is useful to fellow IT Pros, it is not intended to just be a trial/demo of the standard edition (though you could use it as such if you are considering purchasing the standard edition). Whilst some features are only available in the standard edition, the free edition can still save you hours of work tracking down all the services and tasks using a specified account. See below for a summary of the features that can be found in the free edition (and the additional features in the standard edition)
Time Saving - Scan any number of servers to automatically find all Windows services and scheduled tasks and see who they are running as
Import Computers - Import a list of computers to scan from an Active Directory OU, CSV file, or manually type them in
Task Scheduler 2.0 Compatible - Works with Server 2008 format scheduled tasks as well as XP/2003 format
Intelligent - Automatically looks up alternate formats for the username you specify (i.e. searching for DOMAIN\User will also find [email protected])
Fast - Uses native Windows APIs (does not rely on WMI) and multi-threading to query multiple remote servers quickly
Managed Service Account Aware - Works with Managed Service Accounts, allowing you to find and update services running under MSA credentials
Standard Edition
Standard edition includes all of the features included in the free edition listed above, as well as the following features:
Automate Credential Changes - Remotely update any services/tasks you want to change credentials for
Find Specific Accounts Only - Option to find only services/tasks that are running as a specific account and to exclude built in system accounts
Export Results - Export the list of results to native Excel file, CSV file or HTML file
Correct Service Dependency Handling - After updating credentials, dependant services are restarted in the correct order to avoid failures
Automatically Grants Required Rights - Automatically grants the new account the Log On As A Service right on the computer the service resides on
Alternate Credentials - Optionally specify alternate credentials to be used for individual computers in the report
ONE NOTE HOWEVER, it appears the developer has been missing for several years. The site and payment systems work fine (did for me in the US) but you can find stories from other people that, for example they did not download the full set of tools they bought right away and the download links have expired.
