The program also includes a registry cleaner to locate and correct problems in the Windows registry, such as missing references to shared DLLs, unused registration entries for file extensions, and missing references to application paths. The following symptoms may indicate Windows registry issues: Your PC is fairly new but its performance is already slow. Your computer takes forever to start up. Your PC freezes frequently. Your PC crashes without reason. You encounter Windows errors regularly. Your applications open slowly and freeze often. Nowadays, cookies, temporary files, and various other means of tracking your Web footprint are par for the course. Some of these trackers are useful, while others can be potentially intrusive. Thankfully, there are many cleaners out there that help keep your system in check. Smart Uninstaller Pro is one of the better ones for its ease of use and powerful cleaning capabilities. Smart Uninstaller Pro's simple and intuitive layout will appeal to users of all skill levels. Its four features -- Cleaner, Registry, Tools, and Options -- are prominently displayed on the left side of the window. We started with the Cleaner first, which breaks down your cleaning options into two tabs: Windows and Applications. The program works by first analyzing your system and then running the cleaner itself.
