Vista Registry Fixing Software


I tried nortons WinDoctor to help fix any problems with missing shortcuts,missing shared files, etc etc and my pc wouldnt startup the next time! It used to work really well with XP and never did XP not start after WinDoctor,it only speeded the pc up,in my experience.Im reluctant to "try" any other registry fixing software,unless there are some well known Vista registry fixing software that someone can recommend in here ???

Thanks very much for help,in advance
