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

Anonymous

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 have found the same, I have checked and am showing Started and Automatic. I was advised on here but in my question to delete all caches and history, that hasn't made any difference either.

I have just received a reply from bigpippa (at end of this message in italics). I am not very good with computers so have just asked her if I will lose any new or changed documents or emails if I do a system restore to an earlier date .. I am waiting on a reply, which if anyone here can answer that would be great too, then if all OK and I wont lose anything I will try it and see if it helps.

Any other suggestions would be fab .. I will update when I give it a go

Oh, can anyone tell me how to get the threads on here to show the newest first please? I am having to go through 10 pages to get to the latest message, which I am sure can't be right .. can it ?? :-)

Cheers Valerie

I had the same problem so I did a system restore to the day before the update and it was fine but i then had to change automatic update to the one where i choose for myself whether to install the update or not, otherwise it will update again when you log in next time. I will wait until they have sorted this out then install it again.

Hope this helps.

Hi,

We have 2 laptops - today(22/11/2012) both have registered this message. I have followed advice above - notification shown as Started and Automatic. However, re-booting has not resolved the problem. Is there a (working) resolution to this fault? Ta.
