heyy guys For a few days the network icon, the action center icon and also the microsoft security essentials icon goes missing from the system tray. I have double checked that all of the icons behaviours are set to show icon and show notifications. Any help will do.

Here is a link to a program download from Microsoft that should help you. http://support.microsoft.com/kb/945011

It didn't help. I tired the microsoft fix it as well as doing it manually.

This has been a problem for years. The easiest way to get the icon back is to LOG OFF then back on. The icon will reappear.
