Updating the emergency repair data
The emergency repair data located in c:\winnt\repair and on the Emergency Repair
Disk (ERD) is used to restore a Windows NT workstation back to the state of the last
repair update. It is used to search for missing or corrupt Windows NT files and to
restore the registry files, including SAM database, security information, disk
configuration, software registry entries, and other information.
