A brief talk on Windows XP registry backup _ Registration Form

Author: Alpine

Frequent system errors, and sometimes even system crashes, are important to backup, and no one wants the system to crash and have to reinstall Windows XP. You can use different methods to back up your registry, and you can put your backup version on a variety of media, but you must first understand what type of file system your computer network is using. Windows XP supports both FAT and NTFS two different file systems.

Here I'll introduce Fat,fat32 and NTFS.

file allocation table (FAT)

A file system for organizing and managing files for MS-DOS and other Windows operating systems. A file allocation table (FAT) is a data structure created by Windows when you use a FAT or FAT32 file system to format a particular volume. Windows stores file-related information in fat for later use when getting files.

FAT32

A file system derived from the file allocation table (FAT) file system. Compared with FAT, FAT32 can support smaller clusters and greater capacity to allocate disk space more efficiently on FAT32 volumes.

NTFS file system

An advanced file system that provides performance, security, reliability, and advanced features that are not available in a variety of fat versions. For example, NTFS ensures volume consistency through standard transaction log functionality and recovery technology. If the system fails, NTFS can use log files and checkpoint information to restore file system consistency. In Windows 2000 and Windows XP, NTFS also provides advanced features such as file and folder permissions, encryption, disk quotas, and compression. The NTFS file system is a secure file system that does not have easy access to NTFS using other operating systems that are incompatible with NTFS, such as DOS or Windows 95/98/me.

Let me introduce several common methods of backup:

One, Backup utility---Backup to tape or other media

This approach is simple, simply by selecting System state in the backup tree, you can back it up or use the Automated System Recovery Wizard on the Welcome tab of Backup. With the selected ASR (Automated System Recovery), the Navigator creates three backup collections, which you can do only by using the wizard.

Second, use Copy or xcopy for backup

When Windows XP is using the registry, you cannot copy the current registry back, so to repair the registry using copy or Xcopy, you must shut down Windows XP and start another operating system such as the Dos,windows 98/me class. Or a second Windows XP. (It is recommended that you use a dual system for configuration of multiple systems, see "Dual Boot Configuration under Windows XP"). Backing up the registry with copy or xcopy is easier than using the Backup tool:

1, run the Backup program and create the ASR floppy disk

Copy your registry backup to another location in the%SystemRoot%\Repair directory

2, and then use Xcopy to copy all the current registry files in the%SystemRoot%\System32\Config directory. Using the/C option enables Xcopy to ignore errors (this is necessary because the current registry is in use.) Otherwise there will be an error).

Third, the backup method when using fat

Windows XP users using the FAT file system can easily start DOS or Windows 98/me (if you are using a FAT32) by using a floppy disk formatted with the/sys option. Then the DOS command prompt will be displayed, which can easily read and write to the hard disk. To create a bootable floppy disk that is compatible with FAT, simply use the Windows 98/me or DOS Format command plus the/s system option. And then copy the Xcopy (xcopy*.*) to the floppy disk. This floppy disk allows you to start on a Windows XP machine and have free access to all of the fat-formatted drives on that computer. After the startup completes with the command prompt, copying those registry files to a secure location is a simple task that can be replicated to another hard disk, a few floppy disks, a CD-R/CD-RW disc on a zip disk, or other supported media.

Four, using NTFS for backup (not recommended)

NTFS has been described in detail earlier. Files on an NTFS drive can only be written by Windows XP, but not by other operating systems. In order to be able to access the registry files on NTFS, you must install a second Windows XP.

Five, use Regedit to 畚 the registration form

Using Registry Editor (RegEdit), you can create another registry backup for recovery by double-clicking a small icon. If you perform a simple primary step, you can create a backup that includes all registry content in addition to the security and Sam registration keys. The following uses Regedit technology to back up the security and Sam registry keys:

1, run regedit.

2, you can now see my coputer in a highlighted state.

3, select the Export Registry file option in the Registry menu.

4, locate desktop and enter a name for this file, then click the Save button.

5, Exit Regedit.

The Regedit version provided in Windows XP is the registry file that is exported as a Unicode format.

Note that it is particularly important to keep your backup files in a safe place.
