Windows 7: Urgent(accidentally removed the whole start menu and all the icons)

help me please!!!!!!!!!!!

I was ending some unwanted processes in my task manager when i accidentally ended the process for the start menu and icons on my pc. now my screen just shows the background and i can only access stuff through the keyboard. can anyone tell me how to restore the start menu and the icons? please helpppppppppp

Open Task Manager,and from the File menu select New Task. There wrote explorer.exe and hit Enter. The screen should be back again.

Alternatively set back to a previous restore point. In the future it may be good practice if you image your system before making such delicate operations.
