järjestelmäpalautusten

Järjestelmäpalautukset, known in English as system restore, is a feature found in Microsoft Windows operating systems that allows users to revert their computer's system files, installed applications, Windows Registry, and system settings to a previous state. This is achieved by creating and using "restore points." Restore points are snapshots of the system taken at specific times, either automatically by the operating system or manually by the user.

The primary purpose of system restore is to help users recover from system instability or malfunctions caused by software installations, driver updates, or unintended system configuration changes. When a problem occurs, a user can initiate a system restore to roll back the system to a point in time when it was functioning correctly. This process does not affect personal files such as documents, music, or pictures, as it only targets system-related files and settings.

The system restore functionality can be accessed through the System Properties window in Windows. Users can choose from a list of available restore points and select the desired date and time. The system will then restart and apply the selected restore point. While it can be a powerful troubleshooting tool, it is not a substitute for data backup. In cases of hard drive failure or severe system corruption, a full backup is still necessary. It is important to note that system restore can sometimes fail to resolve issues, and in rare instances, might even create new problems if the chosen restore point itself is flawed.
