If invalid registry entries are detected, Windows Registry Checker automatically restores a previous day's backup. Windows Registry Checker automatically scans the system registry for invalid entries and empty data blocks when it is started. This article describes the Windows Registry Checker tool. Files that Windows Registry Checker backs up include System.dat, User.dat, System.ini, and Win.ini. When you start your computer successfully, the Windows Registry Checker tool (Scanreg.exe) creates a backup of system files and registry configuration information (including user account information, protocol bindings, software program settings, and user preferences) once daily.
