Windows Registry is a database that stores settings and configuration information for your computer's hardware, operating system, and installed software programs. Overtime, the registry can become cluttered with obsolete or invalid entries, resulting in slower performance and even system crashes. This is where Registry Trash Keys Finder comes in.

Norton Utilities is a well-known and very classic PC utilities software for DOS and Windows, developed by Peter Norton in 1982 (later sold to Symantec Corporation). It integrates disk editing, disk diagnosis and repair, system optimization, system performance testing, virus detection and removal and many other functions in one place, can help users quickly and intelligently optimize the system, so as to improve user computer performance.

First of all, I have to declare: AppNee has no interest or patience for any all-in-one type of system tools such like System Mechanic. Any similar software will come to the end of a blind alley when they develop to the end - their functions are many but not fine, miscellaneous but not pure, can do many things but none can be done best. Anyway, since our computer needs regular maintenance to keep good performance, so System Mechanic is worth a try. Maybe it's just what you like or need.

Wise Registry Cleaner (WRC for short) concentrates on registry cleaning, optimization and defragmentation, can safely and quickly scan, find the most junk registry data and clean it up. Sure there are so many similar tools, but in the end you will find its effect is more obvious and professional and is well received by beginners and professionals.
