System Restore XP: Easy Way To Retrieve PC Files
Online, October 15, 2010 (Newswire.com) - Stop worrying about the important files and programs, if a system failure or other major problem has occurred in your PC. The system restore feature retrieves PC files and programs to an earlier state when everything on PC was working fine. The purpose of restoring system is to bring the system back to a workable state without re-installing the operating system or loosing the data files from it. Importantly, system restore function should only be used after trying comprehensive methods of troubleshooting. This is because it changes many files and registry entries from the system. In some cases, it might replace more files than needed for restoration. The feature was first introduced in Windows XP operating system.
During disastrous installation or configuration change, system restore roll back Windows' state to a working version without affecting personal data including word document, messages, bookmark list, email-settings, videos, music and so on. System restoration in XP automatically takes snapshots of certain parts known as "system state or restore point". It consists of COM+ Class Registration database, boot files, registry and dynamic system files. These are saved as points from time to time. These points mark configuration places to return in the event of PC problem. Usually, problem occurs during installation of unstable device or any old application. So, the points are created before new device drivers, automatic updates, and some applications are installed.
Based on a file filter driver, the system restore XP watches file changes for a certain set of file extensions. By default, Windows XP enables restoring of system on hard drives especially, if the system possesses 200 megabytes of free disk space available after installation. This space is used for storing the data which is gathered from restore points. The process of saving the restore points continue until space is full. Allocation of more space for this restore feature results in better protection and performance. In case the space is full for points then system restore begins writing over itself with least recent data.
The system restore does not act as a replacement for file backup as it sole purpose is to takes snapshots of computer's configuration and program files. The personal data and information are kept untouched. Therefore, it can be said that this function in Windows XP operating system is one defense line against file corruption.
