Because registry is the database which stores the settings and information for hardware drivers, operating system programs, and non-operating system programs. The smallest unit in registry is value. It contains the basic and the most important information of PC device drivers and all installed software. When a program is running, registry values provide the information of the program to Windows. Then Windows can run it smoothly. But if one value is damaged or contains invalid, incorrect information, it will cause the Windows to freeze up, even crash! Registry is the most important in a computer, but very vulnerable. It can be easily deleted, damaged accidentally by some illegal operations like ending some processes in Task Manager, shutting down computer without exiting all the programs. And it can also be corrupted easily by virus, spyware. You need to repair it regularly to make your computer run smoothly. 2. Other Factors. Dll files, Svchost.exe errors cause 15% Freezing problems.
