Windows 11 and 10 users have reported finding a mysterious ‘inetpub’ folder after installing Microsoft’s April 2025 updates, sparking curiosity about its origin and purpose.
The unexpected folder is empty and appears in the root of the C: drive, even on systems without Internet Information Services (IIS) installed. Typically, the ‘inetpub’ folder is associated with IIS, a web server platform by Microsoft, which uses it to store logs, website content, and server-related files. The appearance of this folder on systems without IIS has raised questions, as it is not clear why it is being created.
Microsoft has confirmed that the behavior is intentional but has not fully explained why the ‘inetpub’ folder is being created. The folder is owned by the SYSTEM account, indicating that it was created by an elevated process during the update. This suggests that the folder’s creation is a deliberate action by the update process.
Users have been advised not to delete the folder, as Microsoft claims it should be harmless. While some users have deleted the folder without experiencing any issues, it is recommended to follow Microsoft’s advice and leave it intact. It is also important to note that no new software is installed with the appearance of the folder, so there is no need to panic.
If you need to use IIS, you can enable it by navigating to “Turn Windows features on or off” within the Windows Features settings. This can be done by pressing the Windows button, typing “Windows features,” and clicking “Turn Windows features on or off” to check if Internet Information Services has a checkmark beside it, indicating that it is enabled.
The reason behind the creation of the ‘inetpub’ folder remains unclear, and users can only wait for Microsoft to provide further explanation. For now, the folder’s presence does not seem to affect system stability or performance.
