I will not waste my time to MITM SSL traffic and break down binary blobs to find out, whether it contains something I just typed. It sends out unwanted traffic when I type into start menu --> onus is on Microsoft to be transparent, what it sends out. And to allow user to disable that behavior.
Windows 10 is harvesting and relaying every-fucking-thing you type on your operating system.
