Windows 11 24H2 users have recently encountered a puzzling phenomenon following the April 2025 cumulative update: an empty folder named ‘inetpub’ has appeared on their system drives. While some users initially perceived this as an error, Microsoft has clarified that this folder’s presence is, in fact, a deliberate aspect of a security enhancement.
The ‘inetpub’ folder, associated with Microsoft’s Internet Information Services (IIS) web server software, has emerged even on systems where IIS is not installed. Initially, there were suggestions to delete this seemingly innocuous folder, but Microsoft has since advised against such actions. The tech giant emphasized that removing the folder could compromise a critical security fix aimed at preventing local attackers from manipulating files or folders on the system.
In a statement to Windows Latest, Microsoft explained that the creation of the ‘inetpub’ folder is a protective measure. “After installing the updates listed in the Security Updates table for your operating system, a new [inetpub folder] will be created on your [system drive]. This folder should not be deleted, regardless of whether Internet Information Services (IIS) is active on the target device,” the company noted. This directive underscores the folder’s role in bolstering security, requiring no further action from IT administrators or end users.
Analysis: What if I’ve already deleted the folder, though?
For those who may have already removed the ‘inetpub’ folder, reinstating it is crucial to maintain system security. The process is straightforward. Users should navigate to the Control Panel, proceed to Programs > Programs and Features, and select the option to Turn Windows features on or off. From there, scrolling through the list will reveal ‘Internet Information Services’. By ticking the corresponding box and clicking OK, the folder will be recreated.
This incident serves as a reminder of the importance of understanding system updates and their implications. While the folder may appear empty and harmless, its role in safeguarding against potential vulnerabilities cannot be overstated. As always, caution is advised when managing system files, particularly in the ever-evolving landscape of software updates.
