Ive only gotten the BSOD a few times on Win10, but there are a lot of shall we say 'insecure' settings by default.
You'll have to go through every menu to turn everything off that wants to 'share' to 'the cloud'.
(MS is probably following Apple and Google.)
(Or AOL/Facebook brand limited internet world surrounded by a corporate fence)

*Microsoft also keeps defaulting later on to worthless Edge browser even after changes are made.
Cough.
(Did they forget to add even a basic options pull down menu or even a save function? Yes they did.)

*Even then, CCleaner finds the IE and Edge files full of data even when they have not been used. Odd.

*The Cortana voice assistant seems to be co-joined with the Windows OS search function.
So if you turn off the microphone/camera with Cortana, you turn off basic OS search.
Those need to be turned off through a series of other menus.
Oh yeah, adding desktop shortcuts to things like the settings menu is now confusing or sometimes not available.

*Crass advertisements and/or notifications to sign up to XBox will remain mandatory and pop up unexpectedly everywhere like a cheap bazaar.
Low class.

TLDR:
More stability. More support. Forced good/bad upgrades. Less privacy. Less customization.
Windows 8 (i.e. Simple Simon game) big colorful buttons "for kids 8-and-up" are still carried over in the start menu.
Even when everything else has become totally confusing for young and old.

(edit: Windoz still seems to be the least-worst of the bunch for now...besides linux....as hard as they try.)
