The Privacy dashboard on Microsoft's website lists recent activity, e.g. visited sites or started applications, even if Activity History is disabled on a Windows 10 device.
Recent versions of Microsoft's Windows 10 operating system support a feature called Activity History that is keeping track of some of the things that users are doing on the device so that they may "jump back".
Which is why I manually disabled several items in the Task Scheduler myself:
"\Microsoft\Windows\Customer Experience Improvement Program": Disable both tasks
"\Microsoft\Windows\DiskDiagnostic": Both tasks disabled
"\Microsoft\Windows\Feedback\Siuf": Both tasks disabled
While I am fine doing this, and had no issues, I don't guarantee that it works for everyone. I just hated the thought of running any data collection processes.
I tried that after the first major win 10 update, and it had some side effects for me. I might have been a little overzealous with some of my other changes like trying to disable cortana.
If you look you can choose only the suggested not all options. I choose only those minimal suggest. You can also easily undo. The first major Win 10 update is years ago too, I never used O&O myself till 1803 so maybe it's better now as well at not being too aggressive.
