Windows Preinstallation Environment
Windows Preinstallation Environment is a lightweight version of Windows used for the deployment of PCs, workstations, and servers, or install, deploy, and repair Windows while it is offline.
From Windows PE, you can: Set up your hard drive before installing Windows. Install Windows by using apps or scripts from a network or a local drive. Capture and apply Windows images. Modify the Windows operating system while it's not running. Set up automatic recovery tools. Recover data from unbootable PCs. Add your own custom shell or GUI to automate these kinds of tasks.
