This application is available for downloading from the link posted below. There is no need to register for a trial period since you'll receive a fully working product but with a few limitations.
My opinion towards this product: I wouldn't recommend using it because it appears to be one of the apps that say it fixes a lot of problems, but actually charges your for real money to fix those problems while other apps do it for free and are more reliable. For example, CCleaner is a good choice when it comes to junk file cleaning and registry cleaning.
