Windows 11 users have noticed an empty folder named "inetpub" appearing after a recent update, which is important for managing logs for Internet Information Services (IIS), even for those without IIS activated. Microsoft has warned against deleting this folder, as it can lead to security vulnerabilities, allowing potential attackers to exploit a "link following flaw." If the folder is deleted, it can be restored by reactivating IIS through the Control Panel under Windows features.
