Vista - "Windows cannot connect to the System Event Notification Service"

After a recent Windows Update, this message occurs when the desktop screen
displays after login:
"Failed to connect to a windows service. Windows could not connect to the
System Event Notification 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 cannot access the system log because the service is not running so I don't
know how to fix the problem. Please advice me how to fix it.

ok olga here is the solution,soo fasten ua sit belt,sorry for my poor english,
the problem u just mentioned is caused by a certain windows updates and it mostly occur in hp computers like mine,so that means the solution is to undo wat u have updated so that u will be back and restored to normal like u were before,now this is how we undo the updates u made,when u turn on ua comp just before the windows starts to load ,just before!!!!!(mark that ),there option in the bottom of the screen which appears for a very short time,very short time,now when these option appear just click F11 INSTANTLY without delaying,then u will be taken to soo called windows recovery(restoring) centre,now from there u can take it by ua own ,that means u will restore ua windows to the day u did the update that screwed you,and this doesnt delete any of ua files so dont worry about that,i hope that will be helpful to u and others cause i had this problem for 2 weeks and i just figured out the solution now and i thought it would be nice to help you too,take care

Sorry, but not updating Windows is not a long-term solution for anything. Poor answer. Find a better one.
