System Tray/Notification Area

I was wondering if there is a way for me to delete items in the notification area/system tray. For example, i had a program on my machine the utilized the system tray. now that i had uninstalled it, i looked into the "customize" option and the program is still listed even though it was already removed. The same thing for another program i used, i didnt install it, it was just a tool that when i extracted out of the zip folder, and clicked on the program icon, it hooks right into the OS (it was an OS enhancement). I deleted that folder since there was no real program to install. That notification is still listed in the "customize" menu.

I hope this is clear enough to describe for anyone who can help me. it isn't a real issue, but i like to keep things tidy on my computer and it just annoys me. Thanks!

this can be done via the registry,and i am sure someone with more knowledge than myself will show you.however as a temporary solution ace utilities 64-bit will remove the past items if you click on the appropriate tab clear past notification items.the software can be downloaded from acelogic.com.i own the software and can assure you that it does work.hope this is of some help.
