Smart PC Privacy Cleaner Pro performed very well in our tests, responding quickly and executing its commands in a very short period of time. It was easy to use, making it a great tool for novices and experienced users. We liked that Smart PC Privacy Cleaner Pro had an option for backing up the Registry before cleaning and had flexible options for scheduling cleanings, cleaning on start-up, and shutting down or restarting your system after cleaning. At the core of your PC's operating system is the Windows registry, a collection of entries for every hardware and software component installed on your computer. Created every time a component is added or changed, registry entries capture vital information and settings that help your system operate smoothly. Over time, as more and more components and applications are installed, upgraded, or deleted, the Windows registry becomes congested with entries that may be obsolete or unnecessary. A clogged registry can lead to erratic system performance and a slower PC.

Smart PC Privacy Cleaner Pro can completely remove more than one thousand commonly-used applications, like Windows Live Messenger, Adobe Reader, Avast!, AVG Anti-Virus, BitDefender Antivirus, ESET NOD32 Antivirus, Eset Smart Security, Kaspersky Anti-Virus, Norton AntiVirus, malicious browser plug-ins and much more applications! The program attempts to be all things to all people, and includes tools that can be split into three categories: maintenance, security, and backup.

Smart PC Privacy Cleaner Pro focuses on the maintenance side of things, and includes a Registry Cleaner and cleaner, a disk defragmenter, a disk repair utility that claims to fix errors before drive failure, an explorer for managing disk usage by file type and size, a memory Cleaner for freeing RAM, a game mode, and a driver updater. Security is not the focus here, but it does include malware protection, secure deletion, and a file encryption utility.
