I had BitDefender 2009 installed on my system, and all was well. However, when I installed BD 2010, several of the tray icons for programs that load upon Windows boot-up were missing. I have tried uninstalling BD 2010, but that did not bring them back. I tried uninstalling and reinstalling the other programs, but that did not bring them back. I have tried deleting both the IconStreams and PastIconsStream keys within the TrayNotify key of the Registry, but that did not bring them back. The programs themselves have continued to load at boot-up and function fully and normally. Only their tray icons do not load, making it inconvenient to use the programs. Some of these programs icons link to hardware drivers, such as for sound cards and video cards. Is there any way to retrieve thes tray icons?
