If you accidentally deleted the mysterious folder Microsoft warned all users to absolutely not delete, the company has now released a PowerShell script to help you restore it. The folder in question, ‘inetpub’, began appearing on users’ system drives (C:\) after the April 2025 security update for Windows 10 and 11.
While the folder does not appear to have any files, Microsoft confirmed that it plays a critical role in enabling protections for CVE-2025-21204, a security vulnerability in the Windows Update Stack.
