What is WinPE?
WinPE stands for Windows Preinstallation Environment (Windows PE). It is a minimal operating system with limited functionality to prepare a device for a Windows installation.
WinPE was not built as a primary operating system for a device, but was created as an independent preinstalled environment and as an integrated component for installation and recovery technology such as an Installation for Windows, Windows Deployment Services, the System Center Configuration Manager Operation System (OS) Deployment and Windows Recovery Environment (Windows RE).
What can you do with WinPE?
