Getting an error "failed to connect to a Windows Service. Windows could not connect to the System Event Notification Service service." at startup

* Original Title: Cannot Connect to the System Event Notification Service

My laptop is consistantly very slow to start-up.  When it does I get the following message:

"failed to connect to a Windows Service.  Windows could not connect to the System Event Notification Service service. This problem prevents limited users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond." 

I have gone through the process of  checking whether the System Event Notification Service is running. The Status is invariably set as "started" and the start up type is "automatic" yet the problem persists. 

What can I do?


Thank you.
