Backups and recovery Windows supports several methods to back up and restore the registry: Windows NT-based operating systems automatically create a backup of each hive (.BAK) in the %Windir%\System32\config folder. Any file can be restored from the Recovery Console. System Restore can back up the registry and restore it as long as Windows is bootable, or from the Windows Recovery Environment starting with Windows Vista. NTBackup can back up the registry as part of the System State and restore it. On Windows NT-based systems, the Last Known Good Configuration option in startup menu relinks the HKLM\SYSTEM\CurrentControlSet key, which stores hardware and device driver information. Windows 98 and Windows Me include command line (Scanreg.exe) and GUI (Scanregw.exe) registry checker tools to check and fix the integrity of the registry, create up to five automatic regular backups by default and restore them manually or whenever corruption is detected. The registry checker tool backs up the registry, by default, to %Windir%\Sysbckup Scanreg.exe can also run from MS-DOS. The Windows 95 CD-ROM included an Emergency Recovery Utility (ERU.exe) and a Configuration Backup Tool (Cfgback.exe) to back up and restore the registry. Go to see how do I guard my windows registry.
