Windows 7: bar at top middle

Hi i m new in al this field, so not aware of proper terms to use.
i hav a dell studio 1555 laptop with windows7 home premium 64 bit installed.
now my problem is that when i brought my laptop few days b4 in the top middle of the desktop i had a bar which included IM, WEBCAB, Media center , audio, etc.. but what i did i dont know but the bar disappeared. it was serving very helpful to me. i am having da taskbar at the bottom but missing that bar top middle aero style.

thats it a dock software.. you can download and install a new one from here!

Download RocketDock - RocketDock.com

May be, but how did it itself disappeared. is it some settings problem, and does it comes with windows itself?

I have seen Dell computers with a "Dell Dock"

I would look in your programs at the start menu for something called "Dell Dock" or similar. It's not a Windows program, but it's probably installed on your computer. It's a Dell program. You probably need to start it, then go into options and make it start when Windows starts if you like it. Good luck

Thank u nate it worked.
