Formatting a laptop can be done when you need to reinstall the Windows operating system or you plan to upgrade to a new operating system. When your laptop is formatted all of the data is cleared from the drive. This is the fastest way to clean a laptop if you want to start with a clean slate, especially if your laptop has been infected by a virus. You can do this by first preparing your laptop and then following a step-by-step process.
