Which one do you use? I 'cleaned' my registry with dtweak free, but when I ran a scan on trial version of supposedly microsoft-certified softwear called RegistryBooster it showed the exact same number of mistakes as pre-clean of dtweak. So.. who should I believe? is RegistryBooster just making numbers up so I buy their softwear?
CCleaner is definitely the most reliable for me I have it on every machine I have ever owned and always put it on friends and families PC's whenever they get new ones.
