So, what is Windows PE used for? With Windows PE, you can: set up your hard drives before installing Windows, install Windows using applications or scripts from a network or a local drive, capture and apply Windows images, modify the Windows operating system when it is not running, set up the automatic recovery tool, recover data from devices that cannot be started, add your own custom shell or GUI to automatically perform these types of tasks. It was originally developed to replace MS-DOS boot disks with a bootable environment that can be loaded from CDs, DVDs, USB flash drives, and so on. Windows PE cannot be used as the primary operating system.
Mostly, it is used to install, deploy, and repair Windows for desktop editions, including Windows 10, Windows Server, and other Windows operating systems. It is a lightweight operating system with limited features. Windows PE is also known as Windows Preinstallation Environment and WinPE.
