Did you expect it not to log stuff? Windows needs feedback on what users did when stuff goes bad beyond reporting through feedback. Most feedback are enhancement requests rather than bugs. Microsoft has the power to log everything with the right configuration but they don't capture every little thing. Only enough to understand how users are interacting with new items.
If you're worried about privacy, the Technical Preview (and the Consumer Preview if they plan to do that phase) are not items you should be using.

This current build (9926) has been relatively stable for me. I've been able to play games across Steam, Battle.net, and stand alone stuff. I've also managed to get CHU running on the new EdgeHTML engine that Microsoft will be using in Project Spartan (had to reset IE to fix it. Still no idea why it goes nuts and not display when logging in sometimes). Note that Spartan is not public just quite yet, but the technical preview of IE11 on the current build is using the same HTML rendering engine that will be put into Spartan so it is a very small taste of what it will feel like. MS stated that Spartan will be available to play around with in the next build (when this will happen though is anyone's guess).
There are some noticeable although small usability changes with how you do stuff. Several users are complaining how ugly the icons look. Many demand transparancy back since it was removed from Windows 8.1. It's interesting to see that the primary concern with the majority is UX presentation rather than underlying functional defects and new features. I guess they don't call it the Halo Effect for nothing.
