Under 'Personalization,' the first setting tailors your 'speech, typing and inking input' to the way you talk, type and write. The first page of settings lists four options that you can toggle on or off, while the second page lists five items. The installation process lets you customize privacy settings at the end or go with the defaults in 'express settings.' We'd suggest taking the extra two minutes to forgo the latter and make your own choices here, or adjusting the options after installation, because Microsoft's default privacy settings might not be as private as you'd like. You have the ability to control Windows 10's data collection, but it takes some doing.

But that future relies on big data - your data - and by default, Windows 10 can track and share the websites you visit, the purchases you make, the places you go, the words you type, the things you say and more. Windows 10 is here, and Microsoft's latest operating system is designed for a mobile-first, cloud-first future, as CEO Satya Nadella puts it.
