rendszervisszaállítás

Rendszervisszaállítás, often translated as System Restore, is a feature available in Microsoft Windows operating systems designed to revert the system's configuration to a previous state. This is achieved by creating and saving "restore points" at specific intervals or when significant system changes are made, such as software installations or driver updates. When a system encounters problems, such as instability or performance degradation, users can utilize System Restore to roll back the operating system to a known good configuration without affecting their personal files.

The process involves selecting a restore point from a list, and Windows then overwrites system files, installed applications, and registry settings with those from the chosen point in time. Personal data, such as documents, pictures, and emails, are typically not deleted during this process, as System Restore primarily targets system-level changes. However, any applications or drivers installed after the selected restore point will be uninstalled.

System Restore is a valuable troubleshooting tool for resolving issues caused by faulty software installations, driver conflicts, or registry corruption. It can also be useful for undoing changes made by malware that might have altered system settings. It's important to note that System Restore does not create a backup of personal files and should not be relied upon as a primary data backup solution. Regular backups of important data are still essential.
