The "inetpub" folder, which appeared after the latest Patch Tuesday update on Windows 11, is part of a security enhancement addressing the CVE-2025-21204 vulnerability that could allow attackers to modify system files. Users are advised not to delete this folder, as it contributes to increased protection. If deleted, it can be restored by navigating to Control Panel > Programs > Programs and Features, selecting "Turn Windows features on or off," checking the box next to Internet Information Services, and clicking OK. This process recreates the folder with the same security protections.
