System Tray Icon Problem -- clue found

[Barry Watzman]

For over a year I have been trying to resolve an issue in which icons
that should be present dissappear from the system tray, including (but
not limited to) the sound mixer (speaker) icon. I've posted here, but
none of the suggestions have helped. I've also searched the internet
and found lots of comments on the speaker disappearance in particular,
but none of them resolved my issue. On my system, more than half of the
system tray icons disappeared.

Well, I've found a clue, or perhaps even a cause, and it appears to be a
bug.

For some reason, the problem is caused by, or activated by, turning on
Universal Plug and play. Specifically, turning on (adding):

Control Panel, add/remove programs, add/remove windows components,
Networking Services, check (or uncheck, to remove) UPnP User Services

This "activates" the problem and causes mysterious disappearance of
system try icons on the next and all subsequent reboots. And, further,
removing this service fixes the problem. And it's repeatable.

Now, the question: Does anyone know why this is happening (did anyone
know that it WAS happening?). And is there an explanation or fix if one
wants both the UPnP services and their system tray icons?

Disable Universal Plug and Play Device Host. Unless you are on a network
you do not need it, even if on a network you may not need it. Make sure
that you disable the SSDP service also.

[[Windows XP includes support for Universal Plug and Play (UnPnP) which
allows UnPnP devices to be connected over a network. There are currently
limited UnPnP devices available and due to a recent security flaw it may be
advisable to disable these services.]]
Completely disable Universal Plug and Play (UPnP)

The problem is that I am on a network, and UPnP is apparently necessary
for voice chat in MSN Messenger to work properly.
