The Windows registry is used by every Windows operated computer since Windows 95. It is is a massive information database which holds data relating to your computer's hardware, software, drivers, and other parts of the system. The Windows registry holds the files which the machines operating system uses to run programs in the start up menu, the data that controls the Windows operating system and all other software. The registry also holds the files relating to many other operations. The registry is one of the most important parts of your computer system and if it sustains any damage, your computer may be disabled.
A variety of registry errors may require repair. Some types of errors are preventable and some errors will occur as a natural fault of the system. Most registry problems can be fixed regardless of cause.
An often occurring cause of certain registry errors is improper computer shutdown. This shutdown may be the result of a power failure or could be caused by a system crash. While your computer is operating, the Windows registry is retained in the memory for quick access. Any changes made to the registry while the computer is operating are copied to the hard drive on computer shut down. An improper shutdown disrupts this feature and as a result leaves incorrect files in the registry or can result in damage to some of the registrys files.
Some other commomnly encountered causes of registry problems are incomplete installation or uninstallation of software, outdated drivers, erroneous file/program associations, and malware or spyware. Some registry errors will not show any error messages and will not cause shutdown of the machine. These errors may work more slowly, and will disrupt your system in a minor way. They may cause slow running of your computer and you may very well encounter problems with use of some programs or in use of some hardware that is involved with incorrect registry data.
