Resolved Icons missing from systray

Hi all
I have a strange problem
Today, when I turned on my computer, only 2 icons appeared in the lower right corner of the screen. I rebooted twice, same results.
It shows the time and windows messenger and Local Area Connection.
Usually it also shows internet connection, speaker, MS Essentials, the USB icon (safely remove hardware) and a Logitech icon.
I got my speaker icon back by going into Control Panel. I also clicked on Security Center; it tells me that I have virus protection running.
How do I get the others icons back, and why did this happen?
Any Idea
Sven

 

They've probably switched to hidden, see How can I hide or view hidden icons in my Systray?

Let us know if that helps.

 

No, thats not it.
i clicked on hide and then on unhide and clicked on apply
no luck

 

I got them back, i downloaded a patch from the below address.
