Do you often hear from experts about WinPE and PE, and sometimes people talk about RE or something? Do you sometimes feel confused?
WinPE is windows preinstallation enviroment, windows pre-installation environment, windows recover enviroment is windows Recovery environment.
As the name suggests, PE is a simple windows environment before installation. This environment is a simple mini system used before or when the operating system is installed, the current PE is very similar to Windows XP or Windows 7 7, with many built-in software. These software are pre-configured by PE manufacturers. New software cannot be installed in PE, so only limited functions can be executed. With everyone's understanding of WindowsPE, many great gods have integrated various drivers, various software, and even PES capable of watching HD videos in PE, but these PES are hard to make a difference, because loading must be fast for PE. Win7PE is usually around MB, which is a little slow, and the startup speed of loading so many drivers is very slow.
WindowsRE is a special PE. After Entering windowsRE, it enters the system recovery interface by default. Technically, PE and RE are the same.
The technical principle of widnowsPE is to install a basic system into an image, create a virtual drive letter in the memory at startup, and then release the image to that virtual disk, finally, start the system. You have also noticed that the started PE does not actually rewrite the PE file, so any modifications to the PE system disk on the PE will not be saved, because of this, PE is stable and suitable for maintenance
