XP system system file damage repair tips

  
Method 1: Start with the original XP drive, select ‘R’ on the first screen, enter the operating system repair, enter the c:\\windows\\system32\\config\\ directory, dir System shows the file found, 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, it appears "can't find the prompt of system.alt", it seems that system.alt is also lost, use the following second method. Method 2: But it doesn't matter, there are other ways. XP system has a system backup under windows\ epair. Also rename system system.old (generally do not directly delete the system file, you can restore it after renaming). Then copy c:\\windows\ epair\\system c:\\windows\\system32\\config\\, prompt to copy a file, restart, and enter the system normally. Method 3: Enter the PE system and directly copy the system over the windows\ epair directory to overwrite the original file. Method 2 and 3, the repair is not over yet, because the file under repair is backed up after the first successful startup after installation, so there is no sound card in the registry file, the relevant driver information of the graphics card. But the driver file is already in the C drive, so just let it find the driver and you can install it. Some people may ask why they do not rename and copy those files directly under DOS. Sorry, in DOS, you want to operate on system files, protected, so you can't. This method of renaming is more convenient than backing up the system file to other folders, and it seems that the system files cannot be copied to other folders, and it cannot be overwritten.
