Windows users usually have at least one Windows rescue disk available, which is a bootable tool in recovery environment. In this environment, there is a number of tools to fix issues on Windows computer or simply diagnose the problem. However, there are also many recovery discs, based on Windows Preinstallation Environment (PE). This disc has the same working environment, great hardware support, as well as enough tools for you to fix the system.
What is Windows PE?
Windows PE, standing for Windows Preinstallation Environment, is a lightweight version of Windows 10 with limited features. You can use it to perform a recovery operation, install full version of Windows 10, copy disk, or repair the system. If you have a Windows PE disc available, it can work with all Windows 10 versions from Home to Enterprise.
But, there is a downside here that WinPE can not be used as a primary operating system. It's created to temporarily replace MS DOS environment that is loaded from USB flash drive, DVD disc, etc. The standard Windows PE version works with all Windows apps, drivers, disks, computer management tools, and so on.
How Does Windows PE Work?
After you know what Windows PE is, let's talk about how it's working. Unlike DOS, Windows PE works with TCP/IP, drivers, etc, making it more advanced over MS DOS. Basically, here are some components creating this environment.
- NTFS file system support.
- Support several drivers for 32 or 64 bit version, depending on PE version.
- Offer a great support for sharing files through TCP IP networks.
- Imitate Windows PE from media like USB flash drive, DVDs, DS and so on.
- WMI (Windows Management Instrumentation) option available.
How WinPE Works (Including How to Boot into Windows PE)
Step 1: Insert Windows PE DVD or USB in the computer and change computer boot order in BIOS.
Step 2: The BIOS loads the boot sector and Boot Configuration Data (BCD) will give the information related to computer hardware.
Step 3: Wait for the control to pass Winload.exe, which is inside Boot.wim. Once it loads all the necessary boot drivers, Windows PE is loaded as well.
Step 4: You computer will load Ntoskrnl.exe kernel and then set up the environment. When done, Session Manager (SMSS) will control all the operations. Any registry file will be loaded so that it can configure the environment.
Step 5: The important services will get started, including security subset. To run a setup, you need to use "HKLM\SYSTEM\Setup\CmdLine" registry. The setup.exe file will be opened so that you can start the Windows installation.
Step 6: if there is no app executed, Windows will automatically run Winpeshl.exe file to perform the command: startnet.cmd. It's a default command to run Wpeinit.exe.
Step 7: After you run all files, wait for the boot process to complete. You can then use Windows PE features as your preference.
