How to get Windows Explorer back after multiple change of file manager?

A few months ago I shifted from Windows Explorer to Explorer++ and then Cubic Explorer. This messed up my registry. And I cant get Windows Explorer back now. It works if I run from Start Menu but not when I click desktop icons like My Computer,Recycle Bin,etc. If unregister Cubic explorer from registry and try to open any desktop icons I get Error as EXPLORER.EXE "Application not found". Please I humbly request your help. This is my first Post so sorry for any mistakes.
