As a computer support professional, it will be your responsibility to recover systems from severe problems when they arise. Windows provides a wide range of techniques for recovering from all types of error conditions. You will need to know which recovery technique is the most appropriate to use in a given situation, as well as to be able to employ it properly. The information and skills in this topic should prepare you to respond in a professional and competent manner to correct system issues, recover the system, and get users working again.
A system restore point is a snapshot of the system conﬁguration at a given moment in time. The System Restore utility monitors the system for changes to core system ﬁles, drivers, and the Registry. It automatically creates restore points that contain information about any changes to these components and stores the restore points on the computer’s hard disk. You can also create manual restore points. Restore points include information about changes to system ﬁles, but not data ﬁles or the contents of the Documents folder. You can use a restore point to restore system settings to an earlier state without affecting changes in user data since that time.

Tips: Restore points also do not completely remove installed software. Use Add or Remove Programs to remove all ﬁles, settings, and Registry entries for an installed application.
