How To Fix The Windows Registry Hive Error - PAKLeet

Most techs with a few years of experience under their belt have probably come across the Windows XP corrupted registry hive problem at some point in their career. When it happens, Windows wont start and will present one of these messages:

•  Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM
•  Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SOFTWARE
•  Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): \SystemRoot\System32\Config\SOFTWARE or its log or alternate

In most cases, Safe mode wont work either. The Uniform Approach to fixing this is by getting into the Windows XP repair console and manually replacing the file with the copy that was created when the system was first installed. However, any software or drivers (depending on whether it was SOFTWARE or SYSTEM that failed) that was installed after that point may not work since the registries for them hadnt been installed back then.
Here is my method that I have been using to fix this. It reverts the registry to only a few days earlier rather than back to when Windows was first installed.

Note: You will need access to a working computer to create a boot CD. You will also need a fairly good knowledge of computers, BIOS and registry editing in order to do this. This article is aimed towards computer technicians.

1. If you don’t have it already, download UBCD4Win using one of the Mirrors here . If you do already have it on a CD, skip to step 3.

To run it, create an ISO and burn it to CD you can read the instructions here. I wont write the instruction here because the ones on the previous link are better and this article is more targeted at computer technicians and most of them already have this CD.

2. Once the CD has been created, goto the BIOS and make sure your CDRom is set as the first boot device. Start up the computer with UBCD4Win in the CDRom and you will have some boot options. Choose the “Launch The Ultimate Boot CD for Windows” option.
It will take a few minutes to load fully, but when it does you should see a Windows XP like interface like in the picture below:

3. In the UBCD4Win interface, goto Start > Programs > Registry Tools > Registry Restore Wizard.

4. The program will then ask you which Windows registry you want to repair. In most cases, it’ll be C:\Windows. Choose the copy of Windows you want to repair and press Next.

5. Choose “Fix the system registry to that of a previous state” and Press Next.

6. You should now see a list registry restore points. Choose one with a date a few days before the issue first occured.

7. Wait a few seconds for it to restore the registry. Press Finish and restart the computer. The issue should now be fixed. If not, it may be a sign of a greater issue like hard drive damage.
