Dear Peter,

I believe that the SENS should be on Automatic and not disabled or manual. I believe that's causing your problem.

Regards,

Marco

Hi Marco, I have this “Could not connect to the System Event Notification Service” problem, however, I got it slightly different with everyone else.
- All the services you mentioned above are starting in my Services
- I still have my desktop, not the blue/black background (it happened a little while in the beginning, but immediately changed to my usual desktop). But all of the usual win7 animation (idk how people call it... aero?) are disappeared. My taskbar & folders look like winXP too.
- I do can only choose 'administrator' option in the beginning. But I still need to 'Run as Administrator' when I use windows features like cmd..?

I kinda realized why this problem occurred to me, however I dont know how to fix it. I think it's either :
- I plugged in my old external HD (i havent use it for so long) to backup my files & shutdown my pc with the extHDD still attached
- I plugged in my friend's flashdisk that's either damaged or broken i dont know, because it wouldnt detect in my pc
- Last week I bought a new memory-pc that's apparently incompatible, after several times trial & error (and lots of pc restarting, pick & plug the ram etc) eventually I go back to my old RAM, but there's something a bit wrong with my pc so I decided to use Tuneup utilities to Clean Disk, Clean Registry, Defragment Registry..... all at one go.
I do think after this on I started getting trouble with Startup (i often had to restart twice to simply get into windows) and the Administrator account start showing up even though I never set my user account in the beginning.
And then idk it looks like everything else could be triggered by the external drivers I mentioned above (extHDD & FD)

Do you think I can still use the hotfix tool? or will it make my pc goes worse?

Dear Lydia,

You can still install the Hotfix if you like but I do not believe it will solve your issues. It seems like, reading your description, that most likely your Windows 7 Operating system is damaged by cleaning the registry. Tuneup Utilities is a great program but can damage your OS when wrongly used. I suggest that you create backup of your files and install Windows 7 again or try to repair your system with in the original Windows 7 dvd. Please follow this link for a step-by-step guide.

So I finally used the hotfix tool, and all my aeros are back and there's no more “Could not connect to the System Event Notification Service” problem. However my computer is still running slow at the startup and I believe it wasn't because of the background program that run in the desktop background. Also my Event viewer log isn't working. I even updated my graphic card already.
The problem is I dont have CD/DVD writer in my cpu and I got my win7 installed from the store where I bought my pc 1 year ago. I guess I will find another way....

Dear Lydia.

I you have a key you can also install windows 7 from another boot device like a USB-stick.

Hi Marco,

For work I needed to analyze slow performance and therefore was using a script which rebooted the computer a 100 times with autologon.
As I was performing this task with remote desktop I didn't see the error you described.
All we noticed was that all of a sudden the script ended and there and we couldn't find a patern in it for troubleshooting,
I've tried the hotfix and the script is still running succesfully.

Thank you for this great pointer!
I saved it as the "NuijensFix" should I come to other weird challenges at work. 🙂
