Benefits Of Windows PE | Troubleshooting Windows Using WIndows PE

Windows PE is a modified version of the Windows operating system that is designed to support installing Windows and troubleshooting and recovering an installation that can no longer boot.
Windows PE was created to help OEMs and IT professionals boot a computer with no functioning operating system.
Windows PE runs every time you install Windows 7. The graphical tools that collect configuration information during the Setup phase are running within Windows PE. In addition, information technology (IT) departments can customize and extend Windows PE to meet their unique deployment needs. Windows PE also provides support for servicing Windows images.
In the past, OEMs and IT professionals often used an MS-DOS-based boot floppy disk to start a computer. However, an MS-DOS-based boot floppy disk has a number of limitations that make it difficult to use for pre-installing Windows or recovering existing installations or data. It has:
  • No support for the NTFS file system.
  • No native networking support.
  • No support for 32-bit (or 64-bit) Windows device drivers, making it necessary to locate 16-bit drivers.
  • Limited support for custom applications and scripts.
The limitations of MS-DOS-based startup disks led Microsoft to develop Windows PE, which is now the primary Microsoft tool for booting computers with no functioning operating system. Once you boot a computer into Windows PE, you can prepare it for Windows installation, and then initiate Windows Setup from a network or local source. You can also service an existing copy of Windows or recover data. Because Windows PE is based on the kernel for Windows 7, it overcomes the limitations of MS-DOS-based boot disks by providing the following capabilities:
  • Native support for the NTFS 5.x file system, including dynamic volume creation and management.
  • Native support for TCP/IP networking and file sharing (client only).
  • Native support for 32-bit (or 64-bit) Windows device drivers.
  • Native support for a subset of the Win32 Application Programming Interface (API).
  • Optional support for Windows Management Instrumentation (WMI), Microsoft Data Access Component (MDAC) and HTML Application (HTA).
  • Ability to start from a number of media types, including CD, DVD, USB flash drive
  • (UFD), and a Remote Installation Services (RIS) server.
  • Windows PE offline sessions are supported.
  • Windows PE images can be serviced offline.
  • Windows PE includes all Hyper-V™ drivers except display drivers.
This enables Windows PE to run in Hypervisor. Supported features include mass storage, mouse integration, and network adapters.

Windows PE Troubleshooting
Troubleshooting. Windows PE is useful for both automatic and manual troubleshooting. For example, if Windows 7 fails to start because of a corrupted system file, Windows PE can automatically start and launch the Windows Recovery Environment (Windows RE). You can also manually start Windows PE to use built-in or customized troubleshooting and diagnostic tools.

OEMs and independent software vendors (ISVs) can use Windows PE to build customized, automated solutions for recovering and rebuilding computers running Windows 7. 
For example, users can start their computers from Windows PE recovery CDs or recovery partitions to automatically reformat their hard disks and to reinstall Windows 7 with the original drivers, settings, and applications.
