The Windows Registry is a general registry of data used by the Windows operating system for almost all of its functions. Without this database, Windows could not and will not function. It stores general system and configuration data in the form of entries and references. When the registry gets damaged, or receives corrupted and invalid registry entries, the computer slows down in its operations. It is akin to a messy manager not getting the work done because of a messy table. When a registry cleaner rearranges the entries in a logical order, the speed of a computer increases (especially in its startup times) and there is a marked improvement in the general performance of the machine.

Reg Cross is among those which can clean the registry of a personal computer; scanning the registry table for errors and automatically fixing the invalid references. It has a good and easy user interface and lets the user know what kind of entries were fixed or repaired. Reg Cross is also one of the fastest cleaner utility programs out there.
