SP 52550: Enable the “System Event Notification” service in Windows

Symptom: When you start the Services applet in “Start -> Control Panel -> Administrative Tools”, the “Startup Type” setting for the “System Event Notification” service will be set to “Disabled”.
Resolution: Modify the system registry settings to enable “Automatic” startup for the “System Event Notification” service.
Additional Information: The “System Event Notification” service tracks system events such as Windows logon, network, and power events. Also, notifies COM+ Event System subscribers of these events. Many applications have processes that are run through the “System Event Notification” service, so it’s recommended that this service be enabled.
