Microsoft recently issued a crucial warning to all Windows 11 users regarding the newly created inetpub folder following the April 2025 Update. Understanding the implications of this folder and how to handle it is essential for maintaining system security.

The Creation of the Inetpub Folder

On April 8, Windows Latest reported that the Windows 11 24H2 update unexpectedly introduced an inetpub folder, typically associated with Internet Information Services (IIS).What’s troubling is that this folder appears even on systems without IIS installed.

Why is the Inetpub Folder Important?

This folder is not arbitrary; it has been intentionally included as part of a security update aimed at addressing the CVE-2025-21204 vulnerability. This flaw could potentially allow malicious actors to alter critical system files, making it imperative that users understand the role of this folder.

A Common Misunderstanding: Deleting the Folder

During initial tests, Windows Latest discovered that deleting the inetpub folder did not cause immediate issues within the operating system. However, this should not be mistaken for an endorsement to remove the folder. Despite Windows 11 permitting its deletion, Microsoft advises against it due to its connection to the ongoing security fix.

Guidance from Microsoft

After feedback regarding user confusion, Microsoft amended its support documents, stating, “After installing the updates listed in the Security Updates table for your operating system, a new %systemdrive%\inetpub folder will be created on your device.” This confirmation emphasizes that this folder is a necessary component of enhanced system security.

What Should You Do If You’ve Deleted the Inetpub Folder?

If you have removed the inetpub folder, the recommended course of action is to uninstall the April 2025 Update and then reinstall it. Simply recreating the folder manually will not adequately safeguard your system against vulnerabilities. It’s crucial to ensure system integrity by following Microsoft’s instructions for updates.

For a deeper understanding of the implications of the April 2025 Update and its associated security patches, check the full advisory directly from Microsoft. It lays out vital information about protections that do not necessitate further action from IT administrators or end-users.
