Windows Preinstallation Environment (also known as Windows PE or WinPE) is a lightweight version of Windows operating system that can be used to boot a computer, diagnose and repair system errors, install or deploy operating systems, and execute other system management tasks. It is a minimal Windows OS with limited services, built on the Windows kernel. WinPE is designed to run from a USB drive, CD/DVD, or other bootable media, and can be used to boot a computer into a Windows environment. It can be used to diagnose and repair system errors, configure hardware, install or deploy operating systems, and execute other system management tasks, such as imaging a hard drive. WinPE can also be used to troubleshoot problems, deploy software applications, and perform other maintenance tasks.
