Registry cleaning and cleaners. What's the deal?

It seems the jury is still out.

Some PC "experts" claim registry should be left alone by general users. But some think otherwise...that even from normal usage, registry can be cluttered with errors and "orphaned" files and extensions that can result in performance decline- ergo, regisrtry cleaning is necessary.

Which came first the chicken or the egg? You question falls into that catagory. That being said, I know for a fact most people in the know would tell you not to use registry cleaners on Vista. It is not needed but may harm the OS. I know for a fact reg cleaners have caused crashes and BSOD's. Dont use them. The one possible exception is Ccleaner, it is very mild and if you know what you are doing, you can set it up to be harmless, but its helpfulness is still in doubt.
For both Vista and Seven, this is all that you need to do, to have a well maintained computer
