Microsoft pushed Windows 10 build 10525 to fast ring insiders a few days ago and since this release is part of the testing program started by the company in October 2014, feedback is all the software giant wants to receive in exchange for you to get early access to preview builds.
So because data collection is a must, build 10525 reset some privacy settings in Windows 10 and switches the data collection configuration to “full.”
While this might sound terrible for many of you, it's not, and what's even more important is that you basically agreed with it when you registered to be an insider.
The Windows Insider program is all about feedback and if you block Microsoft from getting it, there's no reason to continue it.
