Now show me some benchmarks/proof of this effectiveness. I could always say a pineapple is a better heatsink than a Thermalright True 120, but that doesn't prove that is true.
If u knew what 'registry' is , you wouldn't be asking that.
Think literally , tasks of shortcuts , start ups etc. , everything like that works because it is a part of your registry . [I assume you know that

] When u uninstall softwares , what happens to all these registries and all? Although I agree , some apps' uninstallers do clean that too , but the fact is ,
most don't . And if such useless left over registry keys increase in number , don't u think that there would be a change in speed of your computer?? This is just equivalent to having too many useless files in your hdd . And what does a registry cleaner do?
Remove such useless leftover keys . Therefore, there has to be an improvement by the use of registry cleaners.
P.S. If u're still not clear , ask .
Best Registry Cleaner?
none, format and reinstall.
hah , as if u don't need the other files that u have in ur hdd , and enough time for installing the apps which u need daily again and again.

You can use the full version as a 30 day trial.
And it has a comprehensive registry cleaner that's better than anything else on the market.
true , its registry cleaner is pretty good , and you can even browse your registry with a cooler user interface as compared to default (windows') . But still , after experimenting a bit , I found that registry easy
could beat tune up utilities . But yes of course , its worth a try , because of its other features in addition to registry cleaner .
