FastClean PRO is a system cleaner and maintenance tool for Windows. It was designed with the purpose of cleaning up your PC and recovering disk space in order to improve its performance. It handles the most common issues, focusing particularly on removing junk files and clutter that accumulate over time.
FastClean PRO works pretty much like any other PC cleaner available, performing a scan to detect unnecessary files in Windows. It specifically scans your system for shared DLL's, temporary folders, IE cookies, MRU list, among other file types. When the scan is over, the app displays all the found directories along with the number of files they contain and the level of damage caused to your system. Clicking the button to start the clean up brings a registration dialog asking you to buy the application, which means the process won't be completed unless you buy a license.
During the scanning process, the application creates a system restore point in case you want to roll back the changes made by the program. Additional tools include a start up booster to control the programs that start with Windows and a scheduler to program automatic clean ups.
In summary, FastClean PRO has a friendly interface that makes it easy to use and accessible to all users. However, since the trial version does not perform the actual cleaning, there's no way to know if it works as its description states.
