Think of it this way, if a 100, maybe even 1000 people deleted their accounts from a bank, would the bank database server run faster? Of course not, it's dealing with hundreds of thousands of accounts. Your system registry is the same, it has hundreds of thousands of entries. If you right click a file, about 20 or so registry queries are done, how long did it take? I want you to see that cleaning the registry is a futile effort. Read this XKCD. http://what-if.xkcd.com/33/ You cleaning the registry is about the equivalent of removing all the ships in the world from the ocean.
