More on the Windows Registry

As I promised yesterday, here is some more information about the Windows Registry. Today we’re going to talk about backing up and restoring the Registry and we’ll discuss how to do this in different versions of Windows. So, no matter what version you use on your computer, this tip should be able to help you in getting the proper work done to back up and restore your Registry. (Keep in mind that there are two sets of directions for each Windows version).

Before we begin, here is a copy of yesterday’s newsletter, so you can read about the beginnings of the Registry and get a little more understanding of it before starting today’s procedure. Also, please keep in mind that some of the directions get a little advanced, so if you’re not 100 percent sure on how to do them, get some help or stray from doing them at all. Okay, let’s get going!

Backing Up the Windows 95 Registry

1. Reboot your computer and when you see “Starting Windows 95,” press the F8 key. Then choose Safe Mode Command Prompt Only from the startup menu and press Enter.

2. At the command prompt, type the following lines, pressing Enter on your keyboard AFTER each line:

cd windows
attrib -r -h -s system.dat
attrib -r -h -s user.dat
copy system.dat *.bak
copy user.dat *.bak

3. WARNING: These steps make the assumption that you do not have any files named system.bak or user.bak. If you do have files with these names, change the extension in the steps above to something else.

4. Restart your computer.

Restoring the Windows 95 Registry

1. Reboot your computer and when you see “Starting Windows 95,” press the F8 key. Then choose Safe Mode Command Prompt Only from the startup menu and press Enter.

2. At the command prompt, type the following lines, pressing Enter on your keyboard AFTER each line:

cd windows
attrib -r -h -s system.dat
attrib -r -h -s system.da0
attrib -r -h -s user.dat
attrib -r -h -s user.da0
ren system.dat system.daa
ren system.da0 system.da1
ren user.dat user.daa
ren user.da0 user.da1
copy system.bak system.dat
copy user.bak user.dat

WARNING: This will restore the previous backup that you had made. If you chose an extension other than .bak when you backed up the Registry previously, substitute that extension above.

3. Restart your computer.

Backing Up the Windows 98/ME Registry

1. Click the Start button, then click Run.

2. Type “scanreg” (without the quotes) in the field and press the OK button.

3. When the program has finished scanning the Registry for errors, it will ask if you would like to back up the Registry.

4. Click the Yes prompt and the program will create the backup.

5. When it is completed, press the OK button.

Restoring the Windows 98/ME Registry

For Win98, reboot your computer and press and hold the Ctrl key while you’re computer is restarting. Then choose Safe Mode Command Prompt Only from the startup menu and press Enter.

For Windows ME, start your computer with a startup disk. Reboot your computer and hold down the Ctrl key while your computer starts up. Then select Start Computer without CD-ROM Support.

You will now be at a command prompt. Type c:\windows\command\scanreg /restore and press Enter on your keyboard. A screen will appear with a list of the previous Registry backups sorted by date. Using the arrow keys, select the Registry backup you would like to restore and press Enter again. A known previously working Registry backup will have the word “Started” next to the date.

Scanreg will now restore the Registry and check it for errors. When it is done, you will receive confirmation and you can hit Enter to reboot your computer. If you had booted your computer with a floppy, please remove the floppy first before rebooting.

Backing Up the Windows XP/2000/2003 Registry

1. Click on Start, All Programs, Accessories, System Tools and then click on Backup. If you do not see the Backup utility, you will need to install it using your XP or 2003 CD.

2. When the program launches, if you are not in the wizard, select the Backup Wizard Option.

3. When the Wizard opens, press the Next button.

4. Select Only back up the System State Data. Keep pressing the Next button until you see Finish.

5. Press the Finish button to start the Registry backup.

6. When it is completed, you will see a report of the backup. You can then press the Close button and exit the program.

Restoring the Windows XP/2000/2003 Registry

Option 1:

1. Click on Start, All Programs, Accessories, System Tools and then click on Backup. If you do not see the Backup utility, you will need to install it using your XP or 2003 CD.

2. When the program launches, if you are not in the wizard, select the Backup Wizard Option.

3. When the Wizard opens, press the Next button.

4. This screen will list all the known backups that were done previously. Select the System State backup that you would like restored.

5. Press the Next button and then the Finish button.

6. When it is completed, you will see a report of the restore. You can then press the Close button and exit the program.

Option 2 (Only for XP and 2003):

1. Insert your Windows CD into your computer and reboot.

2. When it prompts you to “Press Any Key to Boot from CD,” press any key.

3. When the screen appears that gives you the options to Setup, Repair or Quit, press R on your keyboard to enter repair mode.

4. At the next screen, select the installation of Windows you would like to work on. For most people, there will only be one option.

5. When prompted, enter your administrator password and press Enter on your keyboard.

6. When you get the prompt, type “cd repair” to enter the directory where a Registry backup is stored.

7. Type the following lines, pressing Enter on your keyboard AFTER each line:

copy default c:\windows\system32\config
copy sam c:\windows\system32\config
copy security c:\windows\system32\config
copy software c:\windows\system32\config
copy system c:\windows\system32\config

NOTE: If it prompts you to overwrite the existing files, select Y for yes.

8. When you are finished, type “exit” and press Enter.

9. Remove your Windows CD and reboot.

And there you have it. With these guidelines, you can keep your registry safe and secure.
