I have this same problem. I've only just bought this computer with Vista
Home installed.

Have re-started but that doesn't help.

Is there anything else that can help?!

I've tried Virus & Spy-ware checks and nothing comes up.

I'd appreciate it if anyone could come up with an idea

RE: system event notification service?????

I am having the same problem with all 3 standard user accounts that I setup.
I tried deleteing the accounts and re-establishing them and still receive the
"windows could not connect to the system event notification service."

I have Norton running...is that causing the problem?

Hopefully someone can provide a solution on this problem! I don't want my
kids using the administrator account.

RE: system event notification service?????

I've spoken with friends in IT and they all say there's no fix. I've looked
online - Microsoft & their software development website.

All say good things about SENS - System Event Notification Service as a new
synchronisation management operational software, which to me just means =
can't be fixed cause its part of the core of Vista.

I've provided administrative rights to the other standard user account, but
you can still use the "Parental Controls" for the kids' accounts to track /
content control. However, kids are quite smart, they'll probably figure out
how to disable it before long.

so you're saying that, you can provide administrative rights to standard user
accounts?? That almost seems like its defeating the purpose... but at this
point, it would be better than not having any standard accounts at all...

I'm even having trouble reading this page. Did you ever get an answer to
this question - seems by the # of questions a lot of people are having this
trouble. I'm having the exact same problem and I'm going crazy because my
kids are on my computer. If you received an answer can you tell me what it


In other thread ("standard user loging problems") there was a suggestion to
run the CMD prompt as administrator and run "sfc /scannow". I ran it and
afterwards I could log in with "normal" accounts as well. Again, rebooting
has also helped sometines so I am worried whether this is permanent or
temporary solution. Anyway, if others have success with this, would you
please report it here for the benefit of all?


I just used a system restore from before this mess started
but if anything offical is released explaining the cause and/or cure for this
plz post


I just wanted to confirm that running "sfc /scannow" from the command prompt
has solved my problems in this respect -> and apparantly in permanent way.
Seems like some upgrade pack has messed up to registry.



You saved my bacon! I have been getting a message "Error 193: 0xc1" that
affected the running of my SENS services in Vista and would not allow my
Verizon air card to function, which is vital because I travel every week for
work. I researched almost everywhere on the internet and then I ran your
registry correction suggestion below (sfc /scannow) from command prompt and
everything was immediately fixed.

Awesome! Thanks.

Thank you Troels! I am new to this Vista Community posting area and am
surprised that Microsoft doesn't participate. Clearly this is a pervasive
problem (I've been struggling with it for some time now.) Does MS ever read
these things and let us poor sufferers know they are working on the problems
ID'ed here?

RE: system event notification service?????

I've been following this thread closely as I am experiencing this as well as
a few other annoying glitches with Vista. Yesterday I happened to run a
system restore for an unrelated issue....this morning, to my surprise my son
was using his own account. I couldn't believe my eyes. Who knows how long
this will last, but the only thing I had fiddled with was system restore,
which by the way I happened to select a restore point earlier than when this
system event notification issue crept up.
Good luck...it may work for others.

Re: system event notification service?????

I had the same problem and so tried "sfc/scannow" after opening command
prompt as administrator but the result wasn't what I had hoped for. It
scanned up to 98% and then stopped and this message appeared:

"Windows resource protection found corrupt files but was unable to fix
some of them. Details are included in the CBS.Log
windir\Logs\CBS\CBS\.log. For example C:\Windows\Logs\CBS\CBS.log"

Now, what do I do? :( Anyone know? Help, please! I know a little
(emphasis on 'little'!) bit about computers, but when this message came
up I was stuck.

Re: system event notification service?????

Hey, I think I've found something. How about this post I found on
another site??

It looks good. Perhaps it will work.....when I have more time and
patience!!!? Read the fourth post down by user Iquazee.

'Limited User account cannot log on due to error: \"could not connect
to the system event notification service\" - MSDN Forums'

Is this the solution? Ye gads, I don't even really understand it
totally! :0

I'm sorry for so many posts in so little time.

Re: system event notification service?????

I restored system settings to an earlier point before the problem

I didn't have the login problem, because i am only using one 1
But i got a message when i logged in that said there was a problem with
system event notification service and that none-admin accounts were
unable to login.
every time i logged in to my account, the screen went black for 2
minutes, and when i tried to connect to internet i got an error message
that said "Windows Wireless is unable to start because of an issue with
an software." or something like that.

But after i restored system i didn't get any error messages. I can now
connect to internet, and the screen doesn't turn black for 2 minutes.

Re: system event notification service?????

We too had a sudden system event notification error on an administrator
log in and had the same troubles as you all have listed. We found that
system restore was unsuccessful but...when...we unplugged all peripheral
accessories (USB wireless mouse) included, we were able to restore to an
earlier date and correct issues. We are safe. hopefully you too. Glad to
share ; hopefully helps you too.:)

Re: system event notification service?????

ok everyone 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
