windows 11 26h1

Windows 11 26H1 is a version of Windows 11 that Microsoft is using to test new hardware boundaries, particularly for AI-era PCs and Arm-based silicon like Qualcomm Snapdragon X2 and Nvidia RTX Spark. It has a dedicated Beta channel in the Windows Insider Program for platform-specific hardware, separate from the mainstream 25H2 builds. Known issues include a cumulative update (KB5095051) that can prevent Microsoft Office apps from opening when invoked by third-party applications. Other updates include driver support for the Lisuan LX 7G100 graphics card, Safe OS Dynamic Update KB5095185 addressing Secure Boot certificate expiry, and Insider Build 28000.2333 with improvements to Task Manager, NPU support, camera sharing, and Windows Hello. Windows 11 26H1 is not expected to be a broad feature update for existing PCs.
