Free Registry Cleaner
 

OK ,having been hit with the "Free Download " then spend the next week trying to get rid of a heavyweight virus that won't go unless you cough up £30 quid this actually does work and is FREE I have just installed it and it found 1400 unwanted items in my register. You can back up your register if you thing it better to do it as I have done and every thing is OK

If you are ever stuck again Fordie I can very highly recommend AVG free anti-virus.

Spybot Search and Destory is another great one for fixing registry problems:
