I use the old RegCleaner, but tend not to recommend it, as it's older. There's nothing wrong with it, but I don't fancy someone with WIndows 7 trying it then moaning at me about it not working.

I use ccleaner, which ain't too bad, but i prefer PC tools registry mechanic, which does a more in-depth scan & clean of orphaned reg entries and also will create a system restore point before it cleans if you wish,
But before editing your registry manually or using software always make sure you have a backup so any changes made can be reversed should something screw up, at least then there is a chance of repair without a repair install or re-install of your o/s and programs

Wouldn't fancy re-installing an operating system these days !!
It used to be the case that reformatting the hard disk and reloading the operating system would clear all the problems.

Sensible use of Ghost or Acronis TI or their free alternatives such as Easeus ToDo etc should really eliminate the need to reinstall.

I've seen both RegSeeker and RegCleaner bring systems to their knees. I too would not recommend their general use. CCleaner strikes the right balance between effectiveness and safety.
