What are Windows PE Component Files?
Before we dive into the removal process, it’s essential to understand what these component files are and their role in the Windows PE environment.
Windows PE component files are a collection of essential system files, drivers, and executables that make up the Windows PE image. These files are stored in the Windows PE image directory (usually C:\Windows\System32\WinPE) and are used to boot the Windows PE environment. The component files include:
- System files: These are the core files required for booting and running Windows PE, including the kernel, device drivers, and system services.
- Driver files: These are device drivers that enable Windows PE to interact with hardware components, such as storage devices, network adapters, and peripherals.
- Executable files: These are the programs and utilities that provide functionality within the Windows PE environment, such as the command prompt, disk management tools, and troubleshooting utilities.
These component files are crucial for the proper functioning of Windows PE, and removing them can render the environment unusable.
