What is the function of a Recovery Drive in Windows?

The function of a Recovery Drive in Windows is to save files necessary for recovering Windows after a failure. A Recovery Drive contains a copy of the Windows installation files, which can be used to troubleshoot and repair issues that may prevent the operating system from starting correctly. In situations where the system becomes unstable or fails to boot, users can utilize the Recovery Drive to restore the system to a functional state, either by repairing the existing installation or reinstalling Windows altogether.

This recovery option is crucial for maintaining the integrity of the operating system and ensuring that users have a way to recover their systems without losing data or requiring a complete reinstallation from scratch. By contrast, other options focus on improvements or backups that do not primarily relate to system recovery.
