Where in the registry can I find the definitions of icons in the notification area? I want to start removing icons I hate, like Adobe Reader's etc.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

True. It is a duplicate. Search didn't find the other question when I looked. Apparently running programs can display icons in the notification area. I will hunt down autostart programs in the registry. – Andrew J. Brehm Sep 14 '11 at 14:51
Found the thing. It hid in a Wow64 node of the registry! Why do all programs think that I want them running in the background all day??? – Andrew J. Brehm Sep 14 '11 at 14:57

Notification icons are not kept in the registry. They are added dynamically, by programs that are running at that moment. In other words, you have to configure the programs themselves to stop polluting the notification area.

  • If you have an "Adobe Reader update" icon there, update the damn thing and it will go away. (This applies equally to all "update available" icons. They are there for a good reason.)

For future reference:

Icons in the notification area are displayed by programs running, usually in the background. Those programs are often started by Run entries in the registry.

Look here:

In the HKey_Current_User and HKey_Local_Machine hives.
