Windows could not connect to the System Event Notification Service service.

Every so often, 1 in 50, my laptop is very slow to start-up I get the "Please Wait" before the login screen.  Once I do log in I get the error:  

"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."

Aero seems to be disabled also and cannot be fixed without a restart.  This problem is getting to be bothersome and I need to know if it could be hardware related.  Thank you in advance for you help.

Hi,

Since when are you facing this issue?

Did you make any software or hardware changes to the computer recently?

Check if the System Event Notification Service is running or not. To check for the services

1.      Click on Start

2.      In the start Search box type Services

3.      Right Click on - RUN AS ADMIN

Check if the below mentioned services has the mentioned status and start up type.

System Event Notification Service            Started                 Automatic

Also, check the dependency services that are required for System Restore Service to run.

To check that double click on the service and click on the dependency tab.

For the system being slow you may try to improve the performance by optimizing Windows and check if that helps. Follow the link given below on how to optimize Windows.

The aero issue can be resolved by installing or reinstalling the updated graphics card drivers. You may check if any update for the Graphics card is available for your computer from the computer manufacturer.

    I think this problem causing  you to unable to view the  event viewer because the system event notification service crashed and  also affect  the  windows event log service  also.

    I get all these problems too. I have recently installed a new graphics card, but have all the updated drivers.. However the problems have only arose after installing it.  

    If i go to Services and restart the themes service everything is fine again, but if i log out and come back on its back to the Windows Classic mode.

    As for the long Please Wait before login, i have no clue why it has started doing that. It never use to..

    Regarding the SNES, i9t says its running perfectly, yet i get the pop up box saying cant connect to it, yet after the whole boot has completed and everything has settled, all my notifications are present in the notify section in the bottom right hand corner.

    I recently had microsoft windows updates, some involving the Net Framework.....mebe this is the cause! Is there anywere to unistall these?
