Partitioning in vista:How to partition hard drive or disk in windows vista? The missing icon is not among the hidden icons. It was present in the notification area during the previous Windows session and may be there in the next.
Neither is the problem confined just to when the Windows Shell starts, for although this is typically when most items are added to the notification area, it is not the only time. A good example, though admittedly one that is fading quickly from relevance and which anyway does not apply to Windows Vista, is the addition of a network icon when a user activates a dial-up connection to the Internet.
This case is especially annoying because without the icon in the notification area, the user has no very easy way to disconnect when finished. A distinctive feature of this problem is that when you check the relevant program for its option of whether the icon is supposed to show in the notification area, you find that the program believes the icon is enabled.
Disabling the option and then re-enabling it may or may not make the icon appear. Another distinctive feature is a perception that the problem is timing-related and in particular that Windows has seemed unusually busy at the time the icon was expected to appear.
To tell EXPLORER about the proposed new icon for the notification area, this function sends a window message to the taskbar window and waits for a reply. First is a timeout of 4 seconds, raised to 7 in Windows Vista. Second is that delivery is aborted if the target process seems hung.
As noted above, you may get a satisfactory outcome, if only for yourself, by identifying whatever it is that has kept EXPLORER too busy to receive the message in the allowed time. If it can then be disabled, or made to act either before or after the addition of notification-area icons, then you will escape the problem.
However, the only true solution is to patch the problem away. Experiments with Windows XP confirm that the taskbar window can be busy for more than a minute during startup, most notably because of network discovery. On some such occasions, the signs would be obvious even to novice users, e. In an ideal world, or even one in which problems like this receive perfunctory treatment from those who cause them, Microsoft would by now have introduced configurable options, both for the timeout and for whether to abort sending the message if EXPLORER seems hung.
However, Microsoft is peculiarly uninterested. This matters because of the design of the function. If the function returned a handle that the caller would need for later access to the icon, then programmers would naturally enough check for success or failure, as part of ensuring that they have received a handle.
Going to try this link and I hope to goodness I can get my volume control back! The volume, network and power icons disappeared from my notification area suddenly.

Whether the system displays your notification depends on this state. Notifications sent when the user is away are queued for display, but because you cannot know when the user will return or whether the notification will still be valid at that time, you might consider resending the notification later.
Notifications sent during quiet time are discarded unshown. Design guidelines ask that all notifications be ignorable. They should not require immediate user action. Therefore, no notification is so important that it should override quiet time. Do this for both transient and non-transient icons.
When an application is uninstalled, its notification area icon can still appear to the user as an option in the Notification Area Icons page in the Control Panel for up to seven days. However, any changes made there will have no effect.
