How to Edit the Registry The System Registry is a database used by the Windows operating system. It is used to store hardware, software, and operating system options, settings, and configurations. The registry was originally developed in order to decrease the amount of time that the OS would take to look-up settings while the end-user made selections on the computer. The registry also performs a function as a kernel gateway for the OS. Unfortunately, the longer that you own a computer and add or remove programs, the more junk that collects in your computer's registry which can slow overall PC performance. Additionally, many computer spyware and virus applications make significant modifications to the system registry requiring you to edit the registry to fully recover from the infection.

This allows graceful recovery from inadvertently editing the registry in an incorrect manner resulting in catastrophic damage to the computer's OS. There are two options for user's to do if a backup of the registry is required, first, copy the user.dat and system.dat files to a blank CD or USB memory stick for a full backup. The second way, is to conduct a partial backup of the registry using the REGEDIT application.how to edit the registry
