Windows – Skydrive for desktop not showing icon in notification area

Take a look at Microsoft's KB on the issue:

When you start a computer that is running Windows Vista or Windows 7 for the first time, one or more of the following icons do not appear in the notification area in the lower-right corner of the screen.

• The Network icon
• The Volume icon
• The Power icon

You may also notice that the check boxes for the related system icons are not selected on the Notification Area tab of the Taskbar and Start Menu Properties dialog box. However, the network, volume, and power features function correctly even though their associated icons do not appear in the notification area. You can access these features by using Control Panel.

If you gave your computer enough time to finish the startup service initializations before you restarted it, and one or more of the system icons still do not appear in the notification area after the restart, you can make them reappear by deleting two subkeys from the registry.

Microsoft provides a "Fix It For Me" file that will automatically make the changes needed to fix this problem. You can download the Fix It For Me solution from here, or follow these steps to fix it yourself:

1. Click Start, type regedit in the Start Search box, and then press ENTER. If you are prompted for an administrator password or for confirmation, type the password, or click Allow.

2. Locate and then click the following registry subkey: HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify

3. In the Details pane, click the IconStreams registry entry.

4. On the Edit menu, click Delete, and then click Yes.

5. In the Details pane, click the PastIconsStream registry entry.

6. On the Edit menu, click Delete, and then click Yes.

7. Exit Registry Editor.

8. Either restart the computer or the Explorer.exe process.*

*The easiest way to restart explorer is to click the start menu, press Ctrl+Shift and right-click on the empty area of the start menu and select "Exit Explorer".

Then press Ctrl+Shift+Esc, click File -> New Tasks (Run) and type explorer and click OK. Close the Task Manager when you're done.

You can right click either taskbar, uncheck Lock all taskbars, and then drag the taskbar that includes the Notification Center onto the monitor you want it. Afterwards you can recheck the Lock all taskbars option if you wish.

I've confirmed that this currently works, but have not seen a way to add the notification center to muliple taskbars.
