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.

    Hi, I just made account just to help any of you who have this persistent problem after trying every other solution and didn't work.

    My solution too, might or might not work, since there are many problem that cause this type of problem (hey it's windows ^^ get used to it)

    1. Open START and type in services, then click "Services".
    2. Look for System Event Notification Service, right click then select "properties"
    3. Check if it's already on "Automatic" start up type (don't attempt to start the service manually)
    4. Look into "Log on" tab. Click "This account:" then "Browse". It will open up new tab.

    If you don't have several accounts on your Windows ignore step 6 and 7 then reboot your PC.

    1. Choose Log on as "This account:" and click "Browse..."
    2. Fill in your username and password, apply then close services window then reboot.

    If problem still persist, try winsock reset. If after all these problem still persist, repeat step 4 and revert Log on as "Local system account" then reboot.

    Your PC might be infested with several malware and adware. Try to scan your PC using antimalware of your choice.

    Probably the malware hijack and edit the registry and services.

    This is the solution I found myself after trying every other solution on internet and still doesn't work.

    Hope this will help all of Windows 7 users.

    PS:

    Microsoft Support staff, i have to wonder did you guys ever really help Microsoft user?

    All i found mostly just asking user to submit logs and never provide solid solution.

    To Microsoft and Bill Gates, you guys messed up Windows 10 by being the most intrusive OS of all time, congratz Microsoft!! You've beat Google's intrusiveness.

    Windows 10, where all eyes can look inside of your house through your Windows.

    Thankyou, 4 years later and your careful analysis worked. I unplugged my headphones and reset the sockets and it seems to work.
