How to back up and restore the registry in Windows XP and Windows Vista

Registry Editor is an advanced tool used for viewing and changing settings in your system registry. It contains all the information, settings of your computer. Even your user account username and password is saved in the resgistry (if configured to store in the registry).


As Registry Editor allows you to add/modify registry, it is advisable that you only use it if GUI does not provide the option you are looking for. If you make some incorrect changes, your system may crash and break. So it is always good to make a backup of your registries before making any changes in it.

2. On the Welcome to System Restore page, click Restore my computer to an earlier time (if it is not already selected), and then click Next .
3. On the Select a Restore Point page, click the system checkpoint. In the On this list select the restore point area, click an entry that is named “Guided Help (Registry Backup),” and then click Next. If a System Restore message appears that lists configuration changes that System Restore will make, click OK.

 

4. On the Confirm Restore Point Selection page, click Next. System Restore restores the previous Windows XP configuration and then restarts the computer.


The System Restore tool restores your PC to a previous state (that you selected!), without losing anything, such as documents, history lists, favorites, or e-mail. This method is not reliable if you want to rollback the Registry changes made a longtime ago. So, I would better recommend using the first method (below) for this case.

 

5. Log on to the computer. When the System Restore confirmation page appears, click OK..


Method 1: This method is mostly used when you are making changes to some specific area in the registry, but it can also be used to make full backups.

To backup a selected branch/key, follow the instructions below:

* Click Start, and then click Run.
* In the Open box, type regedit, and then click OK
* Locate and then click the key that contains the value that you want to edit
* On the File menu, click Export.
* In the Save in box, select a location where you want to save the registry entries ( .reg ) files.
* In the File name box, type a file name, and then click Save.

Below the Save as type box, you will see Export Range. There you select the range you want to export. Select All if you want to backup all the settings, or select the second option, Selected Branch, to export only the selected branch.

Registry Backup and Restore for Windows NT/2000/2003/XP

Backing up the registry with ERUNT

———————————-

Note: To ensure proper operation of ERUNT, you should be logged in as
a system administrator.

Start ERUNT, confirm the Welcome message.

Type in the name of a restore folder where the backed up registry
files should be saved, or click “…” to browse your computer’s drives
and select a folder. You can also simply leave the default, which is a
folder named ERDNT inside your Windows folder, the advantage being
that you have access to this folder from the Windows Recovery Console
in case Windows does not boot anymore.

Note that in the folder edit field, ERUNT by default appends a folder
named the current date to the restore folder, which allows you to keep
as many registry backups as you wish in the same restore folder,
separated into the different creation dates. This feature, as well as
the appearance of the date string, can be configured via the ERUNT.INI
file, described later in this document. If you want the registry backup
to be created directly in the folder you select, you can also simply
remove the date from the folder edit field before clicking “OK”.

 

 

Restoring the registry with ERDNT

———————————

Situation: Windows is running normally.

To restore a previous registry backup, open Windows Explorer, navigate
to the folder where you saved the backup to, and double-click the
ERDNT.EXE file to start the restoration program. (Each restore folder
has its own copy of ERDNT.EXE in it.) Select which registry components
to restore, then click “OK” to start restoration. When the process is
complete, click “OK” to restart the computer and activate the restored
registry.

Note: If you experience any problems restoring the registry, please
read “ERDNT technical information” later in this document to learn
what ERDNT is actually doing during the process, or simply read on
through the following emergency scenarios for other ways of restoring
the registry.

Optimizing the registry with NTREGOPT
————————————-

Similar to Windows 9x/Me, the registry files in an NT-based system
can become fragmented over time, occupying more space on your hard
disk than necessary and decreasing overall performance. You should
use the NTREGOPT utility regularly, but especially after installing
or uninstalling a program, to minimize the size of the registry files
and optimize registry access.

The program works by recreating each registry hive “from scratch”,
thus removing any slack space that may be left from previously
modified or deleted keys.

Note that the program does NOT change the contents of the registry in
any way, nor does it physically defrag the registry files on the drive
(as the PageDefrag program from SysInternals does). The optimization
done by NTREGOPT is simply compacting the registry hives to the
minimum size possible.

To optimize your registry, simply run NTREGOPT, click “OK”, and when
the process is complete click “OK” to reboot the computer. You should
do so immediately because any changes made to the registry after
NTREGOPT has been run are lost after the reboot.
