A Top 3 Guide: What is Windows PE and How Does It Work?

By  | 

What is Windows PE? PE (preinstallation environment, or), is nothing but a barebones version of an operating system that is used for OS installation, recovery and troubleshooting. The Windows version, also called Windows PE or WinPE, was originally created to replace MS DOS boot disks that were used for the same purpose. As the name suggests, it creates an environment that allows the user to install an operating system and perform system-level operations such as initiating a setup or copying disk images. What is Windows PE and How Does It WorkOne of the key features of any PE, including WinPE, is that it can be initiated from a USB flash drive, DVD or other deployment media. In contrast to MS DOS, WinPE natively supports file sharing via TCP/IP, device drivers for 32-bit and 64-bit Windows, the creation of NTFS file systems, security tools, image capturing and more.

How Does WinPE Work?

PE is widely used for high level tasks such as system repair, hardware related issue or a simple password reset. For Windows PE to work, the system needs to have storage drivers and a network adapter. You also need to change the boot priority in bootloader prior to initiating WinPE. In order to do this, hit the F2 key when booting up. This takes you to the BIOS menu, where you can change the boot priority. If this step is not executed, your system will boot up from the existing installation of Windows, which you don’t want.WinPE

Once the bootloader settings have been changed and you boot up from your preinstallation disk, the boot sector loads and Bootmgr takes over the boot sequence, and the boot-time configuration data is provided by the BCD store. From here, Winload.exe takes over and loads the hardware abstraction layer, after which the boot drivers and registry hive are loaded. This is the point where Windows PE is loaded. Once the environment is set up by the kernel file (Ntoskrnl.exe), the session manager takes over and lets you configure the environment, after which all important services are initiated. At this point, the process depends on whether you’re doing a Windows installation or simply initiating Windows PE for another purpose, such as password reset, data recovery and so on.
