1 - As mentioned above, the SAM file holds the login name and password, then we Just replace the SAM file is to replace the login name and password. However, the "home" hard disk partition format of this replacement SAM file is the same as your system (see FAT32 or NTFS, you confirm it yourself). It is best that this "origin" system does not have a password, the security settings have not been moved (actually a large part of the PC is like this), of course, the more insurance way is to put all of XP [Win NTSystem 32Config] The file is overwritten in the [C:Win NTSystem 32Config] directory (assuming your XP is installed in the default partition C:),
