Common registry operations

I. Registry detection and repair

1. The system will automatically scan the Registry during startup and automatically fix any errors.

2. when the system is running, you can also check the registry: Run Scanregw, the program quickly scans the registry, and displays the scan results. If an error occurs, the system prompts whether to perform automatic repair, if the registry is not backed up, it can be automatically repaired.

3.when the registration table is incorrect and cannot be automatically repaired and cannot be entered into the system, you can run scanreg.exe/Fix in pure DOS to Fix it. In this way, the Registry repair failure may be caused by system startup by loading wrong modules or applications and virus intrusion through the initialization program system. ini and win. ini.

Ii. Registry backup

The Registry consists of two files: system. dat and user. dat, which are stored in the Windows directory. The format of the exported and imported registry file is. reg.

Run scanregw.exe and the system prompts "you have backed up the system registry today. Do you want to back up the Registry again ?", Select Yes to immediately back up the current system information. At this time, the backup data will overwrite the data backed up when the system is started for the first time on the current day.
