What is Windows PE and How to Use It

Windows Preinstallation Environment (Windows PE) is a lightweight version of Windows used for troubleshooting, development,
and other tasks. However, accessing and fully understanding it can be challenging.

Microsoft describes Windows PE as a lighter, simplified version of the Windows operating system.
It uses the same core elements but with some features removed to keep it streamlined.

This allows Windows PE to load on computers facing hardware and software problems. However, the primary purpose of this is to install Microsoft Windows products. Other reasons for which Windows PE can be used include:

– Installing Windows from a local or external drive
– Modifying the Windows to troubleshoot errors and problems with it
– Setting up system or data recovery tools
– Recovering data from various devices quickly
– Set up Hard Drives, including formatting, partitioning, etc.
– Troubleshooting Windows Startup issues
– Run a simple memory test

How Windows PE Works
Windows PE is a lightweight version of Windows designed for troubleshooting and system setup.
Its use depends on the user’s purpose and goals.

Unlike traditional troubleshooting tools like MS-DOS, Windows PE has a full UI and supports various internet drivers. It can help you:

– It can be installed on a USB, DVD, CDs, etc.
– Windows Management Instrumentation allows you to control Windows API
– Supports file sharing via TCP networks, including full-fledged usage of IP
– Supports Windows x86 and x64 drivers, but that depends on the Windows PE version*
– Create partition as it supports dynamic volume creation, including NTFS and FAT file systems

Windows PE Requirements
Windows PE has minimal system requirements and doesn’t need a hard disk or SSD to run. Its operating requirements include:

– A 32-bit version of UEFI and Bios to run the 32-bit version of Windows PE
– A 64-bit version of UEFI and Bios to run the 64-bit version of Windows PE
– Working memory of at least 512 megabytes, since it runs from memory and not from a hard disk drive
– Network adapter and storage drivers to ensure smooth operation

Limitations of WinPE
Windows PE is versatile for troubleshooting, but it’s not a full operating system.
It can’t be used for general purposes like browsing the internet or listening to music.

Windows PE doesn’t use the Windows Shell, making troubleshooting easier. However, after 72 hours of continuous use,
it restarts the Shell to clear memory. When this happens, all changes are lost, so it’s important to save any work
before the 72-hour mark. Other limitations of PE include:

– Joining a network or domain
– Connecting to IPv3 or IPv6
– Remote desktop and its accessory features
– Running apps from other bits, i.e., 64-bit apps on 32-bit and vice versa
– Using DISM or Appxbundle packages
– Not supporting file or terminal serve use

Conclusion
Creating a Windows PE bootable drive allows you to troubleshoot issues and fix your PC on the go.
It’s also great for development and testing.
