Description from WinZip International LLC“Prevent system crashes and optimize your Windows registry for peak PC performance with WinZip Registry Optimizer, a two-in-one utility that takes the work out of cleaning, repairing, and organizing your PC's registry. 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.”
