Con Collects a lot of user data and sends it Microsoft by default
By default Windows 10 gathers information related to contacts, location, calendar and input (text and touch). The process for opting out of all data collection efforts is both time consuming and requires a reasonable amount of technical know-how.
Con No guest accounts
Windows 10 lacks the ability to set up Guest accounts.
Con Lacks polish
Many interface and functionality changes have not been finalized yet, creating an inconsistent user experience. For example, there are both simplified Windows 10 style settings menus as well as Windows 7 style settings menus that can easily create confusion.
Similarly, many of the bundled applications (People, Photos, Groove, Mail, Calendar, etc) lack functionality compared to their counterparts in previous Windows versions.
Con Forced updates to Home and Pro versions
Since Microsoft has a checkered past in regard to Windows updates, many people worry that a bad patch might break applications, drivers, peripherals or even brick their computers.
Con Start menu lacks expected customization options
It's not possible to cascade menus, pin files, locations or apps to the list (it's possible to pin apps to the live tile section) or add custom menus.
Con No built-in way to play DVDs
Third-party software is required to play DVDs.
