The keylogger and things where with the dev version, this public release has all that removed. It will however send usage and crash reports and anything like every other system out there does if you opt to. There is nothing different about 10 than there is about any other Windows release.
From what I've heard and read, it's not bad at all. It's what 8 should have been, a better version of 7. I will be trying it and getting the free upgrade before next year and the free goes away. I might even make a new partition on my laptop just to run it.
