A backup is something you have to do before you modify anything, not to mention the registration form. So where is the registry? Is it regedit.exe? Oh, of course not.
In the Windows 98/me system, the registry consists mainly of the two files System.dat and User.dat, hidden in C:\windows. Where System.dat contains hardware and software settings, User.dat holds user-related information. (Don't tell me you can't find these two files!) If this is the case, Start menu-Settings-Folder Options, open and select the "View" tab, check the "Show All Files and folders", Hey, go look for it! ）
In Windows 2k/nt/xp/2003 systems, user profiles are saved in the Documents and Settings folder. Includes two hidden files NTUSER.DAT and ntuser.int and NTUSER.DAT.LOG log files; The system configuration file is saved in the system directory (for example, 2K system directory for Windows) system32\ Config, including default, SOFTWARE, SYSTEM, and Appevent. EVT, Secevent. EVT, Sysevent. EVT multiple hidden files and their corresponding. log log files and. sav files.
Automated system backup and recovery
In Win9x, the system automatically backs up the registry files as System.da0 and user.da0.
1. When the system problems, the time into a DOS state, at the command prompt type Scanreg/restore, and then the system will automatically restore, and then restart.
2. Type scanreg/backup at the command prompt, where 5 registry backups are available (the 9X system backs up the most recent 5), and the date before a computer failure is selected.
