Windows PE (Preinstallation Environment) is a lightweight version of the Windows operating system designed for deployment and recovery tasks. It provides a minimal environment that allows users to install, troubleshoot, and repair Windows installations without needing a full operating system. Typically used by IT professionals, Windows PE can boot from various media, such as USB drives or CDs. It includes essential tools and command-line utilities, enabling users to access files, run scripts, and perform system diagnostics. This makes it a valuable tool for system administrators and technicians during maintenance and recovery operations.
