The trouble is caused when UPnP is performing a lengthy scan of UPnP-enabled devices in the local network. This can block the entire tray icon functionality.
To correct this on Windows XP SP2 or SP3 (the option is not available on older versions):
Click on Network Places on the desktop to open it.
In the left pane, under Network Tasks, select Hide icons for networked UPnP devices.
Note: If you're using
Windows Classic folders you'll have to change the Folder Options to Show common tasks in folders to access the Hide... option.
Select Yes to continue if and when you get a warning that the corresponding port will be closed in the firewall.
MagicISO (MagicDisc) goes to the trouble of detecting and actively reporting this
problem to you, while many other programs don't bother. Other tray icons are typically missing too. Usually with this fix, other missing tray icons will reappear.
