Dear Microsoft, This is why people hate you ... and this is a fucking Insider Preview...
Jesus fucking Christ... talk about your sneaky hidden features. There is no real excuse for this other than its been deliberately designed to ensure the vast majority of people leave it on, sending God knows what back to HQ. Most likely in clear text too.
I'm not a conspiracy nut... well, not most of the time, but this makes me instantly want to sandbox this in a VM, sniff every single piece of data trying to escape and go back to Linux only environments.
There wasn't a single one of the 15 options I felt like leaving on as something I would want data leaving my PC containing.
But at least the Start menu is back.... **sigh**
Edit: if this isn't clear in the pictures (lol) this is the Windows 10 installation screens on a 1080p monitor (the resolution was likely 1024x768 due to no drivers yet) and the screen is deliberately not showing a scroll bar and the last option is hidden out of view to turn off.
If you look at the screen padding of this area, given they will have no doubt tested and tested this process on this resolution, you could quite easily have fit this whole section on one panel. Instead we have to scroll, and like most malware application installs, it is just off screen, out of plain sight for no good reason IMO.
