WinGet-AutoUpdate-aaS (formerly Winget-AutoUpdate-Configurator) is based on WinGet-AutoUpdate (WAU) and is dedicated to the approach to bring you WAU in the form of a service (aaS). So this means:
WinGet-AutoUpdate-aaS takes the configuration from Microsoft Intune and applies it to WinGet-AutoUpdate so your users stay up-to-date with their software.
Winget-AutoUpdate-Configurator integrates well into Microsoft Intune by using ADMX backed policies. You can configure nearly all aspects of Winget-AutoUpdate from your Microsoft Intune console and change settings when you need without redeploying Winget-AutoUpdate.
You can also configure your white- and blacklist from within the Microsoft Intune console and do not need to host them on an external data source.

WinGet-Autoupdate-aaS is also available from the Microsoft Store and can be deployed using the Microsoft Store App (new) mechanism:
