Windows users are facing security challenges, including zero-day vulnerabilities and hackers bypassing Windows Defender. Microsoft has removed VPN provisions for Windows Defender and discontinued security support for Windows 10, but users can upgrade to Windows 11 for free. Following the April 8 Patch Tuesday updates, a new folder named "inetpub" appeared on user devices, which Microsoft has warned users not to delete, as it is essential for security protections. This folder is generated after installing updates and is traditionally associated with the Internet Information Services (IIS) web server platform, regardless of whether IIS is installed. If users have deleted the inetpub folder, it can be restored by enabling IIS through the Windows Control Panel.
