Discovering unfamiliar files or folders on your computer can be concerning, particularly because malware often creates hidden files to facilitate infection. For users of Windows 11, the recently emerged empty “inetpub” folder is not a sign of malicious activity; rather, it plays a vital role in addressing a security vulnerability in your system.

The inetpub folder was reported by Windows Latest and was introduced during the latest Patch Tuesday update for Windows 11. This folder is linked to a crucial security improvement concerning an elevation of privilege vulnerability identified as CVE-2025-21204. This flaw in the Windows Update Stack could allow malicious actors to alter system files and folders. However, the exact connection between the inetpub folder’s creation and the patch remains ambiguous, though it has been stated to enhance system protection.

If you encounter the inetpub folder on your system, refrain from deleting it. In the event that you have deleted it, there’s no need to worry—you can restore it to ensure that the necessary security measures are in place.

Steps to Restore the Deleted “inetpub” Folder on Windows 11

If the inetpub folder has accidentally been removed from your Windows 11 device, it is essential to restore it to maintain the effectiveness of the security patch. While recovery of deleted files is typically achievable through the Recycle Bin, File History, or other backup methods, the process to specifically recreate the inetpub folder is as follows, according to guidance from Windows Latest:

1. Navigate to Control Panel > Programs > Programs and Features.

2. Select Turn Windows features on or off to open a dialog box.

3. Mark the checkbox next to Internet Information Services and press OK.

This will regenerate the deleted inetpub folder with the same security measures as the original, ensuring your system remains protected.
