Yes, there are some free Registry tools with good reputations. But. The real question is why do you want one? That is, what problem are you experiencing that leads you to believe that such a tool would be helpful? General Registry "cleaners" simply remove invalid entries. (Some have been known to remove some valid ones as well and actually cause problems.) It takes tons (and tons) of invalid entries to effect XP performance to the point at which it becomes noticible. Most experienced users keep a Registry tool on hand for difficult un-installs and other arcane purposes. CCleaner has a built-in "Issues" tool that does basic Registry clean-up, but even that should be used with care. CCleaner is great for clearing out temp files. Available here:

http://www.larsheder...erunt/erunt.txt The Registry is the very heart and mind of Windows. Nothing happens without it, and changes to the Registry always have consequences. If the solution to a problem requires a change in the Registry, a "cleaner" will not help. That requires experienced and knowledge-able help.
