How to Repair Windows Registry Errors

Windows Registry is a group of data files within the Windows Operating System that contain essential information for running Windows on a computer. Windows Registry runs all programs, user interfaces, and services that the Windows Operating System provides and is critical to a computer’s proper performance. Whenever a program is installed on a computer, Windows Installer places data in the Windows Registry to allow the program to run and access other Windows Operating System components. When these data files are lost, corrupted, or incomplete uninstallations or viruses modify them, the computer may not work properly or experience decreased performance. By using a software known as a registry cleaner, a user can repair the Windows Registry and improve his/her computer’s performance.
