Windows Preinstallation Environment (Windows PE) is an operating system that Windows Setup uses to install Microsoft Windows from build 4001 of Windows Vista and up. Windows Recovery Environment also uses Windows PE.

Description[edit | edit source]

Windows PE is a minimal install of Windows with many files removed. It normally runs on a RAMdisk.
