Recovery after registry damage-registration form

Since Windows 95 system, the Windows system has adopted the Registry management mechanism. The registry data is stored in the following two system files: User.dat and System.dat. The registry is one of the guarantees for the normal operation of Windows systems. Once the registry fails, it can cause the Windows system to not function correctly.

It is based on the importance of the registry, Windows system has taken the appropriate protection measures. The basic method of protection is to back up the registry data files and related INI files of the last normal boot system, and restore the system after the last normal boot configuration once the failure occurs. The following is a description of the recovery method for the registry under Win 98 system and Win 2000 system.

Registry recovery under Win 98 system

In the Win 98 system, the registry recovery is achieved through the use of tool scanreg. The Scanreg command is located in the windows\command\ directory (assuming that the Windows 98 installation directory is Windows).

Each time you start Win 98, the system automatically compresses the system files (these system files including System.ini,win.ini,user.dat and System.dat) that make the computer boot up to a CAB file in an implied directory Windows\ Sysbckup\, and retains the five most recent date backup file Rb001.cab~rb005.cab. By using these systems to back up files, you can restore a computer that does not start correctly to the system settings that you have been able to start any time in the last five times. These system backup files will normally be restored to your Windows 98 system and require a tool provided by Windows 98: Scanreg. With this tool, you can manually back up the system files at any time, and you can restore the registry to the system securely by restoring any of the last five system backup files.

The following is a brief introduction to the use of Scanreg:

Command Format:scanreg/<option>

option has the following options:

Lists the usage of scanreg and related parameters.

Backup backs up the registry and related system files.

Restore selects the backup file for recovery.

Comment "<comment>" adds special notes to the backup file.
　　
Fix Repair registry.

Executing the scanreg command with this parameter automatically takes the following three steps:

Locate the illegal system registry key in the registry;

Check the system registry structure;

Re-establish the system registry.

Running the scanreg command requires Windows 98 startup when you see starting Windows 98 ... The information, press F8 key, in the Boot menu, select Command Prompt only way. After the startup completes, execute the command at the c:/> prompt. If you run the Scanreg command in MS-DOS mode of Windows 98, it automatically enters its Windows operating mode (equivalent to executing the SCANREGW command), checks only for the registry, and does not restore and repair the registry. The execution of the Scanreg command is simple, and you can follow the instructions on the interface. After you execute this command, you will first be sure to check your registry, select Start for a period of time, and if you do not find the error prompts you to choose Create Backup or View Backups ..., select Create Backup You can manually back up the registry and related system files, select View Backups ..., you can see the most recent five system backup files, they are backed up by the time to distinguish, select the backup file to restore, select Restore, You can restore the corresponding date system backup files to your system. If you want to recover the last registry, execute the SCANREG with the restore parameter. The command format is as follows: Scanreg/restore.

Registry recovery under Win 2000 system

In Windows 2000 systems, the SCANREG command is no longer available, and registry recovery relies primarily on the functionality of the Windows 2000 system itself. The specific steps are as follows:

When you see the "Please select Startup operating system" message during computer startup, press the F8 key.

In the Startup menu that appears, use the arrow keys to highlight the Last Known Good Configuration item and confirm it.

Then select the operating system you want to start, confirm.

Depending on the recovery capabilities of the Windows 2000 system itself, the entire registry cannot be restored. This can only be effective when a registry failure occurs when a problem such as a newly added driver does not match the hardware, and does not resolve a registry problem that is caused by a corrupted or missing driver or file. This means that using this registry restore method, Windows 2000 only restores information in the registry key hkey_local_machine\system\ CurrentControlSet. Any changes made in other registry keys remain unchanged.

The above is just the introduction of the Windows system itself provided by the tools or features to restore the registry method, of course, there are many special system tools to maintain the registry, here is not introduced. The registry recovery method that you want to introduce can help you with your daily usage.
