Rebooting, or restarting, your computer involves turning it off and then back on again, which can help resolve minor software issues and apply updates. Resetting, however, is a more drastic action that restores your computer to its original state, often as it was when you first purchased it. This process can involve reinstalling the operating system and may result in the loss of personal data and installed applications. Resetting is typically used as a last resort to resolve significant system issues or to prepare a device for a new user.
