Reliability improvements have been made to the operating system itself, the software and hardware used with the operating system, and how the entire system responds to user actions.

You will benefit from the added reliability in several ways, including: broader application compatibility, improved device and hardware support, side-by-side dynamic link library support that helps your system safely share components, an easier way to close unresponsive applications, system installation and update improvements, backup and recovery improvements, and better support systems.
