This may sound like an advert, but, I assure it is not. There has been a few threads on this subject so I would like to put my two cents in. There is a very simple but effective tool that you can use with complete confidence, It is called Tweaknow Regcleaner. It is a free download from click here and click here This little gem will clean the registry and divide the results into three sections, safe to delete, not safe to delete, and unknown. When the instructions are read it will tell the user what to do, so it can be used either novice, or experienced users alike. You use this progrm to manage the registry not to kill it. There is also a pro version that can be had from the above two sites or from click here for those who choose to do so. I hope this helps. J.B.
