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

This problem just popped up for me. Took forever to boot up and the desktop is in classic mode. I tried resetting Winsock which worked for one reboot and then the problem came back. I reinstalled Windows 7 which worked for one reboot. Then I read something about audio drivers or other drivers possibly being the problem which didn't make sense to me since my drivers were all up to date.

But here is how I fixed it. I did a clean boot using msconfig. I left all of the microsoft services on and disabled everything else. Reboot. The problem was gone. Everything back to normal. So then I decided to try and find out which service was causing the problem so I did another clean boot but this time I enabled my audio driver. And that was it.

PROBLEM SOLVED. For me anyway. Here's the short version

-Go to start

-type msconfig and open

-under General check Selective startup

-uncheck load startup items

-under services tab check Hide all Microsoft Services

-Then click disable all

-reboot

at this point if it worked for you like it did for me you can go through the list of services enabling them and rebooting to figure out which one is messing up your computer. For me it was DTSAudioSvc.

High all,

I think I found the problem. And thus the solution!!!!!!!!!!!!!!!!!

This morning I experienced the same problem as described above. Really annoying because of three things: I bought an SSD to boot up faster; then the error message disappeared way to fast to read it and find a solution!; and if you final rebooted three times to read the message you cannot find "System Event log" to view the problem??? .... That's appreciated Microsoft.....

But via googleing "System Event log" I found this forum :) and as is suspected "System Event log" = Event Viewer. To find the error report do this:

-Select Windows Logs

-Double click System

-Right click on System

-Select Filter Current Log

-Check Error and click on OK

My error is a service control error and it says: The Audio Service service hung on starting. But then why did it hung?...

Looking at the posts many people experience similar problems and some can solve it temporarily. A solution is (de)installing some programme or use winsock reset. Thus some sort of reset does the trick in temporarily solving the problem. But it occures in an irregular fashion. So what is causing it?

Then I remembered that I yesterday turned out the laptop with the earphone/speakers still plunged in. It is horribly stupid to think that leaving the earphone plunged in make your system fail. But then again: it's windows! And also mind that many people listen to music via earphones. On top of that the error report is on the audio service!

As test I rebooted the laptop after using: Command Prompt (Run as administrator) --> netsh --> winsock reset --> exit --> exit. That reboot went smooth. Then I rebooted a second time successfully. Then I plunged in my earphone and rebooted a third time. When the screen got black I unplugged the earphone. This time the problem reoccurred. It is not hard evidence but it sounds illogical logic and it passed my hypothesis. Thats good enough for me. :)

Solution for users:

Unplug your earphone before you shut down the computer

Advise to windows:

Fix this horrible crappy bug
