It is part of the Telemetry utilities that collects usage/errors of your system and reports back to Microsoft. However, there are multiple processes of this feature and the Device Census app is just one process that collects the information. When all of
the data collection is done, another app sends the data to MS if you have approved the "Feedback" feature.
If you disable the Feedback option, that only stops it from sending the data to Microsoft. It doesn't disable the data collecting apps, which is why you still get the pop-up message even though the Feedback option is off.
To disable the data collection, you have to disable the scheduled tasks that starts those processes. Normally the task runs at 3am but if your computer isn't on, it runs when you log in.
In the search box, type "Task Scheduler" or select Start > Windows Administrative Tools > Task Scheduler.
Expand the Task Scheduler Library folder tree to /Microsoft/Windows/Device Information/. Here you will find the "Device" task. Right click the task and choose "Disable".
You might want to look at the other "Feedback" tasks and possibly disable them if you don't want them running.
