Notification area icons missing, even after reset..!

Hello,

My problem is some of my apps that starts with the system have an icon in the notification area (which i set to SHOW ALL) and suddenly few of them do not appear anymore, even after restart or caches cleaning.

I found that using CCleaner and checking "clean notification area cache" make them appear again (after i reboot) BUT sooner after another few reboot they'll disappear again! I tried the bat file to reset notification area history (found on this board) and this one doesn't make them appear again at all..! What can i do?

Thanks.

I checked that, no these apps do not have an option to choose showing or not the system tray. And I tried reinstalling one if them too, no luck with that. I've made some search, many add that issue but no-one solved it

Eraser, Dolby Suround (pcee4.exe) and another i can't remember just now..

These are must common but it actually be any..

This is not the problem. As said it can be any notifications. This is one if there many possible Windows bug.. Though resetting notification icons cache didn't help.

Thanks, I'll try see if there's any, afraid not though. It started very recently, dunno after what.
