Missing System Icons - Volume icon, Power icon, Network icon

This has been a problem for many Windows Vista users - The missing system icons:

Volume Icon
Power Icon
Network Icon

It happens every once in a while, and suddenly you're confronted with greyed out option boxes!

I've searched high and low for a solution on the WWW and there were many ridiculous methods out there that simply won't work.

I've found the following method that worked for me. It doesn't require a reboot.

4.) Exit Registry Editor

5.) Return to the desktop -> Open the Task Manager by pressing CTRL+SHIFT+ESC.

6.) Go to Processes tab -> Locate "explorer.exe" -> click on the "End Process" two times. You will now notice your Taskbar is now missing. No worries.

7.) On the Task Manager -> click File -> click New Tasks (Run) -> type "explorer.exe" -> OK

8.) Exit Task Manager. The taskbar is now back and the missing system icons should now be visible again. DONE!
