Repair your corrupted Windows registry | ArticlesBase.com

January 6th, 2010 in Software | No Comments »

A computer free of errors runs smoothly, with the probability of crashing dramatically lowered. However, over time and continuous use, it develops errors, especially after a number of run-ins with malicious software, like viruses and spy ware. The computer may end up having a corrupted Windows registry, which leads to the dreaded computer crash. By cleaning up the registry, you can protect your files and ultimately, your computer.

Back Up Your Files

Before cleaning the computer's registry, see to it that you have backed up your files. An error in cleaning could easily wipe out your files. Save your computer's contents on a different drive and/or on an external hard drive. That way, you can still recover your files, even if you screw up the registry cleaning process. After backing up your files, close all active programs, since they can interfere with the cleaning.

Registry Cleaning Software

Cleaning the registry, manually is quite tedious, which is why many people rely on registry cleaning software. These programs are available on computer software stores or can be downloaded through download sites like http://www.download.com or through Bit Torrent. Do some research on the product before downloading, since some of them may not be as efficient as advertised. Once you have one installed, just follow as directed by the program. In an hour or two, your computer should be running smoothly.

Manual Cleaning

In some cases, the computer won't open up Windows, which renders some registry cleaning programs useless. You have no other choice but clean the registry, manually. Here's how:

1. Slip the Windows XP CD in your CD drive then reboot the computer.

2. Press “R” when the option appears, opening up the Recovery Console.

3. Choose your preferred means of installing Windows, then supply the administrator password, if your computer was assigned one. You'll then be taken to the command prompt, which comes as a black screen with a blinking cursor.

4. Enter the following data:

md tmp

copy c:windowssystem32configsystem c:windowstmpsystem.bak

copy c:windowssystem32configsoftware c:windowstmpsoftware.bak

copy c:windowssystem32configsam c:windowstmpsam.bak

copy c:windowssystem32configsecurity c:windowstmpsecurity.bak

copy c:windowssystem32configdefault c:windowstmpdefault.bak

delete c:windowssystem32configsystem

delete c:windowssystem32configsoftware

delete c:windowssystem32configsam

delete c:windowssystem32configsecurity

delete c:windowssystem32configdefault

copy c:windowsrepairsystem c:windowssystem32configsystem

copy c:windowsrepairsoftware c:windowssystem32configsoftware

copy c:windowsrepairsam c:windowssystem32configsam

copy c:windowsrepairsecurity c:windowssystem32configsecurity

copy c:windowsrepairdefault c:windowssystem32configdefault

5. Type “exit” after.

6. When your computer is booting up, press F8 then choose Safe Mode.

7. Log in as the administrator then activate System Restore (Start – Search – Search for System Restore).

8. Set a restore point, so your current settings are saved.

9. Copy the following files to C:WindowsTmp:

_REGISTRY_USER_.DEFAULT

_REGISTRY_MACHINE_SECURITY

_REGISTRY_MACHINE_SOFTWARE

_REGISTRY_MACHINE_SYSTEM

_REGISTRY_MACHINE_SAM

10. Once done, rename the files you just inputted, based on the last word of their file names. For example, _REGISTRY_USER_.DEFAULT should be renamed to DEFAULT and so forth.

11. Repeat steps 2 and 3.

12. Enter the following commands on the command prompt:

del c:windowssystem32configsam

del c:windowssystem32configsecurity

del c:windowssystem32configsoftware

del c:windowssystem32configdefault

del c:windowssystem32configsystem

copy c:windowstmpsoftware c:windowssystem32configsoftware

copy c:windowstmpsystem c:windowssystem32configsystem

copy c:windowstmpsam c:windowssystem32configsam

copy c:windowstmpsecurity c:windowssystem32configsecurity

copy c:windowstmpdefault c:windowssystem32configdefault

13. Repeat step 5.

14. Once your computer boots up, repeat steps 7 and 8.

Cleaning windows, as you can see, is quite tedious. If you're not adept at navigating and tweaking Windows, you might as well have a programmer or a computer technician perform the task. You won't pay much, since the job is elementary for them anyway.
