Windows 10 Diagnostic Data

OK so I did some deep diving into the app Windows Diagnostic Data Viewer that’s part of the new Windows 10 Fast Ring Build that was released recently and to be honest, it was an eye-opening experience.

If I am using the app correctly (and I most likely am) there is a toggle that will show you what is being collected and sent based upon the diagnostic level you have chosen (Basic vs Full). After seeing some of the data that’s being sent to Microsoft I would suggest that everyone, and I do mean EVERYONE changes their diagnostic mode to Basic. Do not pass Go, do not collect $200… CHANGE IT TO BASIC RIGHT NOW!!! I’m not even kidding here!

Now onto why. Oh man, yeah… this is a doozy even by my standards. So I opened Microsoft Edge and went to my web site, closed Microsoft Edge, and then launched the Windows Diagnostic Data Viewer app and did a search for a String in the data containing my domain name. Much to my horror, it was there!!! And worst of all, it was being sent to Microsoft as part of a sampling group. Microsoft even told me that my system was part of the sample group. Now I don’t know if this system is part of the sample group because I am running a Fast Ring build. No, I don’t use this system for every day usage; it’s only a VM for testing purposes.

With all of that said, I then toggled the mode to Basic meaning it would show only the data that your system is sending if your system was set to Basic mode and sure enough, the most damning of data was not included in the data set. Let me repeat that… in Basic mode the most damning of data was NOT included in the data set. Below are links to the two data sets.

Basic Mode Data
Full Mode Data

As you can see between the Basic Mode and the Full Mode that the Full Diagnostic Mode collects and sends a hell of a lot more data than Basic Diagnostic Mode. I have uploaded both files for people to see exactly what is being collected and sent to Microsoft.

Let’s just put it this way… if you have any want for privacy, even a little bit, Full Diagnostic Mode is DEFINITELY something you want to avoid like the plague!
