Windows Recovery Environment (WinRE) is a simplified version of Windows that provides access to recovery tools to diagnose and fix problems with the Windows operating system.
WinRE is used to repair Windows Startup issues, run CMD without booting the computer, and revert to the previous Windows version.
It is enabled on all desktop editions of Windows 11, but malicious software can sometimes disable it, leading to errors during PC resets.
To enable WinRE on Windows 11, users can use Command Prompt to check the status and enable it manually, following specific commands.
