How to Enable and Disable Reliability Monitor Data Collection
This article applies to Windows 7 and Windows Server 2008 R2.

In Windows 7 and Windows Server 2008 R2, you can view information about a computer’s reliability and problem history in Control Panel\System and Security\Action Center\Maintenance\Reliability Monitor. Incidents and estimated reliability are displayed in an interactive graph. A diagnostic infrastructure uses built-in testing and diagnostic scenarios to examine the current system state, and provide warnings or resolutions. The Reliability Analysis Component (RAC) supplies data about software installations and upgrades, application and operating system errors, and hardware issues to Reliability Monitor. This data is used to calculate Reliability Monitor’s System Stability Index.

The data that is displayed in Control Panel is collected by the RacTask scheduled task.
