How to Delete Diagnostic Data in Windows 10

As you may already know, Windows 10 comes with a telemetry and data collection feature. It collects a lot of diagnostic data and sends it to Microsoft. According to the company, this data is used to improve the product's quality and the user experience. Along with the recently added Diagnostic Data Viewer app, Microsoft has added the ability to remove the Windows Diagnostic Data that the operating system has collected from your device. Here is how it can be done.


Windows Diagnostic Data

Windows 10 comes with a number of tools to manage the diagnostic data. There is a web-based app, Microsoft Privacy Dashboard, which allows the user to manage many aspects of your privacy in the new operating system.

The options "Diagnostic and usage data" can be set in the Settings app one of the following levels, as described by Microsoft:

  1. Security
    In this mode, Windows 10 will send minimal data to Microsoft. Security tools like Windows Defender and Malicious Software Removal Tool (MSRT) will send a small set of data to the company's servers. This option can be enabled only in Enterprise, Education, IoT and Server editions of the OS. Setting the Security option in other Windows 10 editions has no effect and automatically reverts to Basic.
  2. Basic
    Basic information is data that is vital to the operation of Windows. This data helps keep Windows and apps running properly by letting Microsoft know about the capabilities of your device, what is installed, and whether Windows is operating correctly. This option also turns on basic error reporting to Microsoft. If you select this option, they'll be able to provide updates to Windows (through Windows Update, including the Malicious Software Removal Tool). However, some apps and features may not work correctly or at all.
  3. Enhanced
    Enhanced data includes all Basic data plus data about how you use Windows, such as how frequently or how long you use certain features or apps and which apps you use most often. This option also lets Microsoft collect enhanced diagnostic information, such as the memory state of your device when a system or app crash occurs, as well as measure reliability of devices, the operating system, and apps. If you select this option, Microsoft claims to provide you with an enhanced and personalized Windows experience.
  4. Full
    Full data includes all Basic and Enhanced data, and also turns on advanced diagnostic features that collect additional data from your device, such as system files or memory snapshots, which may unintentionally include parts of a document you were working on when a problem occurs. This information helps Microsoft further troubleshoot and fix problems. If an error report contains personal data, they won't use that information to identify, contact, or target advertising to you. This is the recommended option for the best Windows experience and the most effective troubleshooting.
