In this article I’ll show you some system error repair techniques which can help resolve DLL issues, device driver issues and registry problems. This includes options which are freely available as part of the Windows operating system as well as commercial tools that can automatically repair registry and OS program faults.

#1 Using application updates (free)

The easiest way to fix DLL issues or damaged registry keys is to install updates to problematic applications. If errors relate to a specific program or piece of hardware then you can check for updates directly from their website to see if an updated version/patch is available. The updates will overwrite faulty settings/drivers/DLLs.

Problems with the operating system can also potentially be fixed by getting the latest Windows updates. Note however that this will only download and install a subset of changed files so may not be able to rectify all issues.

#2 Running a registry cleaner or PC repair scan (commercial)

A great many system errors are often due to damage to operating system programs and the registry file. In particular, the registry file contains configuration settings for every application running on the system so can quickly become corrupted or damaged as applications are removed, programs are installed and viruses corrupt registry keys.

Fixing the registry manually is recommended against because of the danger of changing shared key settings which would affect several applications at once. Instead use a registry cleaner (e.g. Registry Easy) or PC repair tool (e.g. XP Repair Pro) to fix the damage for you.

#3 Restoring system files from backup versions (free)

The final system error repair option is to use Windows own System Restore functionality to rollback key operating system files and the registry to earlier working versions. Windows maintains these versions on free disk space and creates new date-stamped version of them every time Windows update is run or you install new programs.

You can access the program while Windows is running (accessories/system tools/system restore) which allows you to pick a previous date-stamped backup version to reload. The healthy files are loaded up and the system restarts for them to take effect.

The only real side effect of doing this is that changes to the registry file made after the backup version will be lost. This is a minor setback as you can of course reinstall any programs once again for the settings to be updated.
