Microsoft Windows 11 includes several features that are not enabled by default, which can hinder user experience: 1. System Restore: Allows users to create restore points for system recovery but is not enabled by default due to disk space concerns. 2. End Task Feature: Enables users to right-click on unresponsive apps in the taskbar to force quit them, but requires activation through Settings. 3. File Extension View in File Explorer: Users must manually enable the display of file extensions for better file management. 4. Hibernate Mode: A power-saving option that saves the system state to the hard drive, not readily accessible in power settings and requires enabling through Control Panel or command line. 5. Start Menu on the Left: The Start menu is centered by default, but users can adjust it to the left through Settings, which some long-time users prefer.

A vulnerability in Windows, tracked as CVE-2024-43461, has been reclassified as previously exploited after being used in attacks by the Void Banshee APT group to deploy information-stealing malware. Initially disclosed in September 2024, it was confirmed to have been exploited before the fix was issued. The flaw was discovered by Peter Girnus from Trend Micro, who noted that it was used in zero-day attacks alongside another vulnerability, CVE-2024-38112. The attacks involved malicious HTA files disguised as PDFs, utilizing braille whitespace characters to hide the true file extension. Following the security update, Windows now accurately displays the .hta extension, although the presence of whitespace may still mislead users. Microsoft also addressed three other actively exploited zero-days during the September Patch Tuesday.

The Cybersecurity and Infrastructure Security Agency (CISA) has directed U.S. federal agencies to strengthen their systems against the Windows MSHTML spoofing zero-day vulnerability identified as CVE-2024-43461. This vulnerability was initially deemed non-exploited by Microsoft but was later confirmed to have been exploited before its patch. Attackers, including the Void Banshee hacking group, used this vulnerability to install information-stealing malware by deceiving users into opening malicious files disguised as harmless documents. CISA has included this vulnerability in its Known Exploited Vulnerabilities catalog and has mandated that federal agencies secure their systems within three weeks, with a deadline of October 7. Additionally, Microsoft has addressed three other actively exploited zero-days in its September 2024 Patch Tuesday updates.

In Windows 11, users can change file extensions easily to correct mislabeling issues. File extensions, such as .png or .mp4, indicate how the operating system should handle files, while file types refer to the actual format of the file. To view file extensions in File Explorer, users can navigate to the folder, click on View, and select Show > File name extensions. To change a file extension, users highlight the file, rename it by deleting the old extension and adding a new one, and confirm the change. For changing multiple file extensions at once, users can use the Command Prompt by navigating to the folder, typing CMD in the address bar, and using the ren command. Changing file types or formats requires a conversion tool, such as iLoveIMG, where users can upload files and convert them to the desired format. It is advisable to review converted files before deleting the originals.
