Microsoft is known to collects various pieces of data about your device and your behavior with it to understand what features are working, which ones are not, and what changes are needed.
Ultimately, this telemetry data helps to make Windows 10 a better product. However, for many people, this is also a privacy concern, which is why starting with the Windows 10 Redstone 4 update, Microsoft is introducing an option that allows users to view the raw diagnostic data that the company collects about your device. In addition, in order to give more control to users, it’s now possible to delete that telemetry data that has been collected from your computer.
In this guide, you’ll learn the steps to delete the Windows 10 diagnostic data collected from your device.
Although you can’t stop Microsoft from collecting data about your device, you can delete the already collected diagnostic data using these steps:
Click on Privacy.
Click on Diagnostic & feedback.
Under “Delete diagnostic data,” click the Delete button.
Once you’ve completed the steps, the diagnostic data will be erased from your device. If you’re using Windows 10 with a Microsoft account, then you may need to sign into your account to delete additional data.
It’s not absolutely clear, but as I understand it, this feature should delete the data stored on your device and from the Microsoft servers.
If you don’t see these settings, it’s likely because you’re not running Windows 10 version 1803 or later, which is expected to rollout in spring 2018.
