Several of my notification tray icons (gotten to by clicking the up arrow-->customize) are odd. CCleaner is listed but it has the Java icon. Windows Task Manager has no icon next to it. There is one listed, hpvncwin4.exe, that has the FreeAgent icon and I can find no description of what this is by Googling. It just showed up in the last day. That worries me a bit.
Why exactly do these get corrupted?
I tried running CCleaner "Tray Notifications Cache" and it found nothing to clean.
Should I care? Should I reset using this tutorial (I'm not sure I understand about killing explorer.exe)? Notification Area Icons - Reset
Or how about this one, found it here too: http://forums.orumph.com/viewtopic.php?f=6&t=6
