Clean up your computer registry

21 Nov

A computer free of errors runs smoothly, with the probability of crashing massively lowered. However, as time passes and continuous use, it develops errors, particularly 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 alternative 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 applications

Cleaning the registry, manually is quite tedious, which is why probably the vast majority of people rely on registry cleaning software. These programs are available on computer applications stores or can be downloaded through download sites like “” 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:\windows\system32\config\system c:\windows\tmp\systems.bak

copy c:\windows\system32\config\applications 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

delete c:\windows\system32\config\systems

delete c:\windows\system32\config\software

delete c:\windows\system32\config\sam

delete c:\windows\system32\config\security

delete c:\windows\system32\config\default

copy c:\windows\repair\systems c:\windows\system32\config\system

copy c:\windows\repair\software c:\windows\system32\config\software

copy c:\windows\repair\sam c:\windows\system32\config\sam

copy c:\windows\repair\security c:\windows\system32\config\security

copy c:\windows\repair\default c:\windows\system32\config\default

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 paradigm Restore).

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

9. Copy the following files to C:\Windows\Tmp:






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:\windows\system32\config\sam

del c:\windows\system32\config\security

del c:\windows\system32\config\applications

del c:\windows\system32\config\default

del c:\windows\system32\config\system

copy c:\windows\tmp\software c:\windows\system32\config\applications

copy c:\windows\tmp\systems c:\windows\system32\config\system

copy c:\windows\tmp\sam c:\windows\system32\config\sam

copy c:\windows\tmp\security c:\windows\system32\config\security

copy c:\windows\tmp\default c:\windows\system32\config\default

13.    Repeat step 5.

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

Cleaning windows, when you can see, is quite tedious. If you’re not adept at navigating and tweaking Windows, you may 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.
