Windows 11 has elevated system requirements, necessitating four times the memory and storage for AI-driven applications. It can technically run on a minimum of 4GB of memory, but current hardware pricing is challenging due to a silicon shortage affecting various memory types. A retro hardware enthusiast named Omores installed Windows 11 on a DDR1-based system using an ASRock ConRoe865PE motherboard, Intel Core 2 Quad Q6600 processor, 3GB of DDR1 RAM, and an ATI Radeon HD 4650 AGP graphics card. He overcame the lack of AGP support in Windows 11 by using legacy drivers, achieving satisfactory performance for older applications and games. However, Windows 11 version 24H2 requires SSE4.2 CPU instructions, which are not supported by processors from the AGP era, making version 23H2 the last compatible release for such systems.

Microsoft will begin rolling out the May 2026 Security Update for Windows 11 on May 12, 2026. Key features of this update include: 1. Xbox Mode: Transforms PCs into a console-like experience, prioritizing system resources for gaming and freeing up to 2GB of memory. 2. Voice Typing Improvements: Redesign of Voice Typing elements on the touch keyboard. 3. New Arabic 101 Legacy Keyboard Layout: Available for addition from the Region page in Settings. 4. Drop Tray Changes: Renamed from Drag Tray and can be disabled in Settings > System > Multitasking. 5. Taskbar AI Agents Support: Allows monitoring of AI agents directly from the Taskbar, starting with the Microsoft 365 Copilot app. 6. Debloat Policy with Dynamic List Support: Enables administrators to specify additional apps for removal beyond the default list. 7. Windows Driver Policy Update: Changes how the kernel manages trust for third-party drivers, eliminating default trust for cross-signed drivers. 8. Batch File Security Changes: Enhances security for batch files and Command Prompt scripts, with an option for a hardened processing mode. 9. Format FAT32 up to 2TB: The format command-line tool now supports formatting volumes up to 2TB using FAT32.

Microsoft will enforce a new mandate requiring all hardware drivers to comply with the Windows Hardware Compatibility Program (WHCP) standards starting April 1, 2026. This change will eliminate the "cross-signing" system that allowed older drivers with expired certificates to remain trusted. The enforcement of WHCP certification will apply to various versions of Windows 11 and Windows Server 2025. Users may face blocks when installing older drivers on new systems, but existing installations will not be immediately disrupted. Microsoft plans to introduce an "allow list" for vetted legacy drivers to ensure essential equipment remains operational during the transition. The initial rollout will occur in "evaluation mode," allowing Microsoft to monitor driver behavior without blocking software. For corporate environments, Microsoft offers "Application Control for Business" to allow specific software while maintaining security measures.

On March 26, 2026, Microsoft announced that starting with the April security update, it will eliminate trust in kernel drivers from the previous Cross-Signed Program for Windows 11 versions 24H2, 25H2, 26H1, and Windows Server 2025. Only drivers that have passed the Windows Hardware Compatibility Program (WHCP) or are on Microsoft's allow list will be allowed to load by default. This change aims to enhance security by establishing a robust chain of trust and addressing vulnerabilities associated with old kernel drivers. Users of older hardware that rely on specialized drivers may face challenges, as drivers not WHCP-signed or explicitly allowed will be excluded from the trusted zone.

Microsoft is transitioning to a universal printer driver system to address issues related to legacy printer drivers in Windows. Starting with Windows 10 version 21H2, a universal printer driver compatible with Mopria standards has been integrated and is being enhanced through updates. A phased approach to legacy printer drivers will begin in January 2026, when Windows Update will stop allowing new legacy drivers for Windows 11 and Windows Server 2005. Existing drivers for older printers will continue to function. In July 2026, Windows 11 will prioritize the universal driver over legacy drivers, and by July 2027, updates for legacy drivers will be limited to security fixes. There is no set timeline for the complete discontinuation of old printers and their drivers.

Microsoft has confirmed that if an older printer is currently functioning within the Windows ecosystem, it will continue to do so for the foreseeable future. The company clarified that it has not ended support for legacy printer drivers, despite earlier indications that V3 and V4 drivers would no longer be supported starting in January. However, as of January 15, 2026, new legacy drivers will be approved on a case-by-case basis for Windows Update.

The PC market is experiencing a significant shift in 2025 due to the end of support for Windows 10, which is set for October 5, 2025. Windows 11, launched in 2021, requires a TPM 2 for Secure Boot, limiting compatibility to newer devices. Microsoft is phasing out support for older devices due to security concerns, and while older peripherals may still work, they won't receive updates. Microsoft offers extended support options for Windows 10 users, including continued security updates for home users until October 2026 and an Extended Security Updates subscription for corporate users. The transition has led to increased interest in new PCs with neural processing units (NPU) for AI workloads, with support expanding to Intel and AMD systems. The integration of AI capabilities into PCs is being promoted, although current offerings may not incentivize IT departments to invest in NPU-enabled devices. The end of support for Windows 10 has influenced PC purchasing behaviors, resulting in increased shipments as manufacturers prepare for US tariffs. IT leaders must manage their device ecosystems carefully, as unsupported Windows 10 machines could become targets for cyber threats.

Microsoft has ceased support for Windows 10 and released a significant Patch Tuesday update addressing several zero-day vulnerabilities, including CVE-2025-24990, which involves a legacy device driver that has been completely removed from Windows. This driver, the Agere Modem driver (ltmdm64.sys), supports hardware from the late 1990s and early 2000s and has not kept pace with modern security practices. The removal of the driver is a strategic decision to reduce security risks associated with outdated components, as patching such legacy code can lead to instability and may not effectively resolve vulnerabilities. Another vulnerability addressed in the update is CVE-2025-2884, related to the Trusted Platform Module (TPM) 2.0 reference implementation. Additionally, CVE-2025-49708, a critical vulnerability in the Microsoft Graphics Component with a CVSS score of 9.9, poses severe risks by allowing a full virtual machine escape, enabling attackers to gain system privileges on the host server from a low-privilege guest VM. Security experts recommend prioritizing patches for this vulnerability to maintain the integrity of virtualization security.
