Analyze Hardware and Software problems in Windows 7

Reliability Monitor is an advanced tool that measures hardware and software problems and other changes to your computer. This helps IT professionals better manage the stability of machines in their organization. Reliability Analysis Component (RAC) aggregates, analyzes, and correlates problems at the operating system and application levels. It calculates a stability index that indicates overall system stability over time. RAC also keeps track of any important changes to the system that are likely to affect stability, such as Windows updates, application installations, and driver installations.

The Reliability Monitor is intended for advanced computer users, such as software developers and network administrators.
