XP system file Corruption repair Tips

Method One: Start with the original disk XP optical drive, select ' R ' in the first screen, enter the operating system repair, enter into the c:\windows\system32\config\ directory, dir system display found the file, the file is not lost, just damaged. Then enter: Rename system system.old (rename the registry file) Rename System.alt system (System.alt is actually a copy of the registry file) to rename the copy to the original. At this time there is "unable to find the System.alt hint", it seems that the System.alt also lost, use the following second method.

Method Two: But it doesn't matter, there are other ways. The XP system also has a system backup under Windows\repair. The same rename system System.old (generally do not delete systems files directly, after renaming can be restored back again). Then copy C:\windows\repair\system c:\windows\system32\config\, prompted to copy a file, reboot, normal access to the system.

Method Three: Enter the PE system direct copy windows\repair directory of system overwrite original file.

Methods two and three, repair is not finished, because the file under repair is installed after the first successful startup after the backup, so the registry file does not have a sound card, graphics-related driver information. But the driver file is already under C disk, so just let it find the driver can be installed.

One would ask why the files were not renamed and replicated directly in DOS. Sorry, in DOS to the system files to operate, protected, so can not.

This renaming method is more convenient than what is said on the network to back up the system files to other folders, and it is as if the systems files could not be copied to other folders or overwritten.
