Microsoft recently released the cumulative update KB5055523 for Windows 11, mainly fixing vulnerabilities and improving system performance.
However, many users found an empty folder named 'inetpub' in the root directory of the C drive after installing the update.
The "inetpub" folder is usually associated with Microsoft Internet Information Services (IIS), a website and service hosting platform developed by Microsoft.
By default, IIS is not enabled in Windows systems, and users need to manually enable it through the 'Turn Windows features on or off' dialog.
The inetpub folder is used by IIS to store website content, logs, and other server-related files, but after this update, this folder will be automatically created even if IIS is not enabled.
In actual testing, deleting this folder did not cause any issues with the use of the system, so this is likely a small bug inadvertently created by Microsoft.
