Microsoft has confirmed a major kernel security update for Windows 11, revoking trust in older drivers signed through an outdated cross-certification program. The update will ensure that Windows 11 accepts only software that has passed the Windows Hardware Compatibility Program's testing standards. This change aims to counter piracy attempts, particularly against a hacker known as DenuvOwOA, who bypassed Denuvo's anti-piracy protection by manipulating the embedded hypervisor and loading unsigned or vulnerable drivers. The new security policy will block the execution of such code, making existing hacking methods obsolete. The rollout will begin in compatibility assessment mode for Windows 11 and Windows Server & Hosting, with a hard block activated only if no stability issues are detected. Corporate clients can manually add certificates through the Application Control for business tool, while gamers will find it increasingly difficult to run hacked games relying on a modified hypervisor.

Crimson Desert, developed by Pearl Abyss, will use a minimalist anti-piracy approach by relying on basic tools from the Steam platform and not implementing Denuvo protection. This decision may allow third-party groups to easily bypass these measures upon the game's release. The gaming industry has seen vulnerabilities in anti-piracy systems, as demonstrated by the launch of Resident Evil Requiem, which was pirated within 24 hours using a new method to bypass Denuvo. A free version of Crimson Desert will be available on March 20, but its financial success will depend on factors like game quality and technical optimization, as players often prefer to buy legitimate copies for a better experience.

Microsoft's Hyper-V is a hardware virtualization platform integrated into Windows 11 Professional, Enterprise, and Education editions, allowing users to host multiple virtual machines (VMs) on a single computer. It operates using a type 1 hypervisor directly on hardware, enabling VMs to share resources like CPU, memory, and storage. Hyper-V includes features such as dynamic memory allocation, software-defined networking, and saved checkpoints. IT administrators may need to disable Hyper-V due to compatibility issues with third-party virtualization software, high-precision applications, or driver conflicts. Disabling Hyper-V can also affect security features reliant on it, such as virtualization-based security (VBS) and Device Guard. Methods to disable Hyper-V include: 1. Using the Windows Features dialog. 2. Executing a PowerShell command: Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All, HypervisorPlatform, VirtualMachinePlatform. 3. Running a DISM command: dism /Online /Disable-Feature /FeatureName:Microsoft-Hyper-V-All /FeatureName:HypervisorPlatform /FeatureName:VirtualMachinePlatform. 4. Using the bcdedit command: bcdedit /set hypervisorlaunchtype off. 5. Modifying Group Policy to disable VBS. 6. Editing the Windows Registry to disable VBS or Credential Guard. For multiple managed computers, administrators can create and execute a PowerShell script or use Group Policy Objects to streamline the process. Testing in a controlled environment is recommended to ensure desired outcomes without compromising security or functionality.

Microsoft has blocked credential autofill functionality in Windows 11 as part of the February 2026 Patch Tuesday updates to address the critical vulnerability CVE-2026-20804, which allows unauthorized access by tampering with Windows Hello authentication. This vulnerability was first identified in August 2025 and allows local administrators to inject biometric data. The restriction was documented in the January 2026 Patch Tuesday release notes. Enhanced Sign-in Security (ESS) operates at a hypervisor virtual trust level but is limited by hardware compatibility issues, particularly affecting AMD-based systems. Post-update, credential dialogs do not respond to virtual keyboard inputs from remote desktop or screen-sharing applications, preventing autofill during remote support sessions. Microsoft has provided a risky workaround that allows applications to operate with elevated administrator privileges, but this reintroduces the vulnerability. Organizations must now choose between disrupted remote support workflows or risking exposure to credential injection attacks, leading to operational challenges for IT teams and help desk staff.

Microsoft has added a "Virtual Workspaces" page to the Settings app in Windows 11, allowing users to manage virtualization capabilities. The latest cumulative update has refreshed the Settings app for easier navigation. To enable virtualization features, users must open Settings, click on System, select the Advanced page, and then click the Virtual Workspaces setting. Features include Containers, Guarded Host, Virtual Machine Platform, Windows Hypervisor Platform, and Windows Sandbox. Users can also activate Hyper-V features, which include Hyper-V GUI Management Tools, Hyper-V Module for Windows PowerShell, Hyper-V Hypervisor, and Hyper-V Services. To disable virtualization features, users follow the same steps and turn off the feature before restarting the device. Users can also enable or disable features via the "Windows Features" page and PowerShell.

Legacy Update has enhanced its archive of files previously available on Microsoft's Download Center, consolidating resources from various sources, including the Archive Team's MDC project and the Internet Archive. This update supports a wide range of Windows versions, including Windows 2000, XP, Vista, 7, 8, 8.1, 10, and 11, across all editions and processor types. The archive provides access to older software, such as Office 2003 service packs and XP Mode for Windows 7, as well as tools for running legacy applications. There is a noted transition towards Windows 10 IoT LTSC due to concerns about Windows 11's performance.

A writer from MakeUseOf uninstalled all third-party antivirus programs from his Windows PC and found that the system performed better and appeared more secure with Microsoft’s built-in Windows Defender. The experiment highlighted Defender's effectiveness, showing fewer false positives, improved performance, and no noticeable decline in protection. Independent tests ranked Defender highly in real-world protection, and it achieved perfect scores in recent AV-TEST evaluations. The removal of third-party antivirus software led to a significant decrease in CPU and RAM usage, with idle consumption dropping from 15-20% to under 5%. Despite 121 million Americans still using third-party tools, there is growing consideration for Defender due to its free and efficient nature. While Defender excels in many areas, experts caution that it may not fully protect against zero-day vulnerabilities, and layered defenses are still recommended. The antivirus market may face disruption as integrated protection becomes more common, and user feedback indicates a preference for free alternatives that match or exceed the performance of paid solutions.
