The registry is a database (a collection of information) used by the Windows operating system to store information necessary to configure the computer for one or more users, applications, and hardware devices. The registry contains a very large number of individual settings and the number of files that make up the Windows registry vary depending on the version of Windows.
Often, the settings in the registry become corrupted. There are a number of reasons that this happens including faulty uninstallers, power outages, and the improper use of registry cleaners.
EarlsHelpDesk.com can repair a large number of common registry problems, although there are times when a complete factory reset is the only effective way to completely fix the registry. If you suspect problems with your registry, call the help desk before you attempt cleaning the registry yourself.
