#Reason windows

The administrator can use Windows Error Reporting to send the SSD data to a central location, or to Microsoft. An SSD file is created only if the SSD policy is enabled on the system. For example, after logging in, the system displays a dialog box reporting the unplanned shutdown if the policy has been enabled. Notification and reporting options are controlled by a set of policies. If this flag is not present, the shutdown was unplanned. This file contains system state information such as the processes, threads, memory usage, and configuration. The system generates a System State Data (SSD) file.
