The Windows Registry is the configuration database in all 32-bit versions of Windows that contains settings for the hardware and software in the PC it is installed in.
In all versions of Windows, the Registry can accumulate obsolete and nonfunctioning entries. Older versions of Windows, in particular, were notorious for this, often ending up with Registries containing huge numbers of erroneous entries. This slowed computer operations; and could even lead to crashes.
