Windows registry is a complex database that enables software and hardware to store settings and preferences. We should take the backup of the registry before making any changes in the registry values. Registry backup avoids the improper function of certain programs. Registry backup can be done by the following two ways :–
Method 1 :–
1. Click on “Run” tab
2. Type “regedit” in the “Run” box and press “Enter” key.
3. There you will find all the registry entries and then click on “File” tab.
4. Click on the “Export” option and the save registry to desired location
Method 2 :–
1. Click on “Start” and then click on “Run”, type %SystemRoot%\System32\Restore\Rstrui.exe, and then click “OK” tab.
2. Now, you will find “System Restore” page, click on “Restore my computer to an earlier time” (if it is not already selected), and then click on “Next” tab.
3. On the “Select a Restore Point” page, click the system checkpoint.
4. On the Confirm Restore Point Selection page and click on “Next” tab. System Restore restores the
previous Windows XP configuration and then restarts the computer.
5. Log on to the computer. When the System Restore confirmation page appears, click on “OK” tab.
Now, we will discuss about the methods to repair the Windows registry and error messages that generally appear during corrupted registry values. When we try to restart the Windows XP based computer then we may receive one of the following error messages :–
1. Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM
2. Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SOFTWARE
3. Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): \SystemRoot\System32\Config\SOFTWARE or its log or alternate
4. System error: Lsass.exe
When trying to update a password the return status indicates that the value provided as the current password is not correct.
Windows registry repair generally includes three methods and the one of them is the following :–
We need to insert the Windows XP startup disk into the floppy disk drive or insert the Windows XP CD-ROM into the CD-ROM drive and then restart the computer.
Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted to do so.
1. When the “Welcome to Setup” screen appears, press “R” key to start the Recovery Console.
2. If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console.
3. When you are prompted to do so then type the Administrator password. If the administrator password is blank, just press “ENTER” key.
4. At the Recovery Console command prompt, type the following lines, pressing ENTER after you type each line:
md tmp
copy c:\windows\system32\config\system c:\windows\tmp\system.bak
copy c:\windows\system32\config\software c:\windows\tmp\software.bak
copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
copy c:\windows\system32\config\security c:\windows\tmp\security.bak
copy c:\windows\system32\config\default c:\windows\tmp\default.bak
