Windows Server 2022 Nears End of Mainstream Support

Organizations using Windows Server 2022 will lose mainstream support on October 13, 2026, although security updates will continue through extended support until October 2031. Customers are encouraged to plan for an upgrade to Windows Server 2025 to avoid potential security vulnerabilities and complications in future migrations. Microsoft recommends early evaluation and testing of Windows Server 2025 to ensure compatibility and smooth transition. Additionally, support for the Azure Edition’s hotpatching capability has been extended to October 2027, providing some customers more time to strategize their migration. However, remaining on Windows Server 2022 means missing out on new features and enhancements.

Windows Server 2022 reaches end of mainstream support next month

Microsoft has announced that mainstream support for Windows Server 2022 will end next month, transitioning to an extended support phase that lasts until October 2031. Windows Server 2022 was released in September 2021 and will receive its final mainstream support update on October 13, 2026. After this date, it will continue to receive essential security updates at no extra cost until October 14, 2031. Hotpatching for Windows Server 2022 will be available until October 2027 for Datacenter: Azure Edition. Microsoft encourages administrators to upgrade to Windows Server 2025, which began rolling out to Windows Insiders in January 2024 and is expected to be generally available by November 2024. Windows Server 2025 will have mainstream support until November 13, 2029, followed by five years of extended support until November 14, 2034. A 180-day trial of Windows Server 2025 is available through the Microsoft Evaluation Center.

Microsoft reveals why 32-bit Windows was limited to 4GB RAM, and it wasn’t a technical limit

32-bit Windows is commonly thought to be limited to 4GB of RAM due to its 32-bit address space, but this overlooks the role of Physical Address Extension (PAE), which allows access to more than 4GB of RAM on compatible processors. PAE enables 32-bit x86 processors to use 36-bit physical addresses. Windows allocates a 4GB virtual address space to each 32-bit application, with 2GB reserved for the application and 2GB for system use. Windows Server 2003 SP1 Enterprise can support up to 64GB of RAM, while the Datacenter edition can handle 128GB. Microsoft did not extend this capability to consumer editions due to the complexities and potential issues with hardware drivers, which often assume a 32-bit framework. Modifying drivers for PAE can be challenging, as incorrect assumptions about physical and virtual addresses can lead to memory corruption. To mitigate risks, Microsoft capped physical address space at 4GB in Windows XP SP2 and Windows Server 2003 SP1 Standard Edition. Server environments typically have more controlled hardware selections, allowing for the use of drivers that are tested for compatibility with addresses exceeding 4GB. Microsoft began discouraging the production of 32-bit systems in 2020 and ended 32-bit edition production with Windows 11.

AI vendors are turning to custom hardware as Microsoft winds back the clock on Windows

This week, insights into datacenter technology reveal a shift in GPU dominance, with companies exploring alternatives. Cerebras, founded by Andrew Feldman, has developed chips the size of dinner plates that contain 44 gigabytes of ultra-fast SRAM, circumventing high-bandwidth memory supply constraints. In 2024, Cerebras launched an inference server that processes tokens faster than any GPU configuration, utilizing structured sparsity and partnering with AWS and AMD. The latest Cerebras chips, CS-4 systems, feature a modular architecture that doubles performance and bandwidth. Google is also moving towards custom silicon with its Tensor Processing Units (TPUs), while Marvell competes with Broadcom in providing IP for custom chips. Waymo announced a custom machine learning accelerator for its autonomous vehicles to enhance compute density and address limitations of previous FPGA use. On the software side, Microsoft is reintroducing the ability to move the taskbar in Windows 11, responding to user feedback after nearly five years. This change reflects Microsoft's focus on user experience amid competition from alternatives like macOS and Linux.

Windows Server 2022 reaches end of mainstream support in 60 days

Microsoft has announced that the mainstream end date for Windows Server 2022 is set for October 13, 2026, after which it will enter extended support until October 14, 2031. Windows Server 2022 became generally available in September 2021 and is part of the Long-Term Servicing Channel (LTSC) offering, which guarantees a decade of support. Microsoft recommends upgrading to Windows Server 2025, which will be generally available in November 2024, and will reach its end of support on November 13, 2029, with five years of extended support until November 14, 2034. A free 180-day trial of Windows Server 2025 is available. Additionally, hotpatching for Windows Server 2022 will be extended until October 2027 for Datacenter: Azure Edition systems. The free Windows 10 Extended Security Updates (ESU) program has been extended by an additional year, and Windows 11 23H2 Enterprise and Education editions will end updates on November 10, 2026, with a recommendation to upgrade to Windows 11 25H2.

Windows 11 24H2, Windows Server 2022, Windows 10 Ent. LTSB 2016 get 60-day cut off warnings

Microsoft has issued a 60-day notice regarding the end-of-life dates for several products, following a previous 90-day warning. Mainstream support for Windows Server 2022 will end on October 13, 2026, affecting all editions. Users of Windows 11 version 24H2 Home and Pro, as well as Windows 10 Enterprise LTSB 2016, will stop receiving updates. Microsoft recommends upgrading to Windows Server 2025, with an extended support phase lasting until October 14, 2031, for those unable to upgrade immediately. Windows 11 version 24H2 users must upgrade to version 25H2 to continue receiving updates, while Enterprise and Education variants will have a grace period until October 2027. Organizations using Windows 10 Enterprise LTSB 2016 should transition to Windows 11 Enterprise LTSC 2024, with Extended Security Updates available for purchase for those who remain on the older system. A 180-day evaluation build of Windows Server 2025 can be downloaded for compatibility testing.

Microsoft keeps Windows Server 2022 hotpatching alive into 2027

Microsoft has extended the availability of Windows Server 2022 hotpatching until 2027, specifically for the Windows Server 2022 Datacenter: Azure Edition. Mainstream support for Windows Server 2022 will end on October 13, 2026, while extended support will last until October 14, 2031. Hotpatching allows administrators to apply security updates without server downtime, although quarterly cumulative updates requiring a reboot will still occur. This feature is exclusive to Azure Edition users, with no similar support for on-premises users of Windows Server 2022. Additionally, hotpatch updates are being introduced for Windows 11 24H2 Enterprise clients and are now the default for Windows Autopatch.

Hybrid AI Agents, Orchestration, and the Real Reason Microsoft is Fixing Windows 11 ⭐

Over the past weekend, the author reviewed session videos from Build 2026, focusing on Windows 11. The sessions were categorized into three areas: Windows app development, developer productivity, and agentic AI. The introduction of hybrid agents, which combine local AI sub-agents, was a notable development. Microsoft's partnership with Qualcomm led to the launch of Windows 10 on Arm-based PCs branded as Always Connected PCs, which evolved into Copilot+ PCs with Nuvia-powered chips for Windows 11. The Copilot+ PCs emphasize on-device AI experiences through powerful neural processing units (NPUs). The introduction of second-generation Snapdragon X2-based PCs is underway, although adoption is slower than expected. Microsoft confirmed that Windows 11 will integrate AI agents, including local AI agents and hybrid agents. The capabilities of local AI models are being enhanced, and Windows AI APIs will now support CPUs and GPUs. New Nvidia chipsets will enable large language models to run locally on PCs. The orchestration of local and cloud AI components is essential for efficient AI workload management. Microsoft is addressing user pain points to support a robust local foundation for hybrid AI, aiming to improve Windows 11 overall.
