Looking for a good Registry Cleaner

My PC has Run Time Errors. Games like Silkroad Automatically force close.
so i need a Registry Cleaner
search from google I have find this:
http://www.speeduppc.net/bestregistrycleaner
Is it the best one?

I was told by someone who knows more than me that registry cleaners were all pretty much the same and that they didn't work that well. I use a registry locker but that's for different reasons.

It sounds like you have more of a memory problem if it's game related. Post the errors or search them on Google.
