Which Windows feature allows users to restore their computer to a previous state?

The feature that allows users to restore their computer to a previous state is System Restore. System Restore creates restore points at scheduled intervals and before significant system changes, such as software installations or Windows updates. If a system becomes unstable or experiences issues due to these changes, users can utilize System Restore to return the computer to an earlier state where it was functioning correctly without affecting personal files. This capability is vital for troubleshooting and recovering from problematic updates or software that may hinder system performance.

System Refresh, though related, focuses more on reinstalling Windows while keeping users' files intact, rather than strictly reverting to a previous state. File History is concerned with backing up and restoring personal files rather than the entire system state, while Device Manager is a tool for managing hardware devices on a system and does not deal with system restoration.
