Additional Information:

The User Data Access service enables apps to access structured user data, such as contact info, calendars, messages, and other content. UWP apps need this service because they run in a sandbox and cannot access the data the way desktop applications do.

If you stop or disable this service, UWP apps that use this data might not work correctly.

The User Data Access service is a per-user service, which is created when the user logs in and is stopped and deleted when the user logs off.
