Microsoft has released Windows 11 26H1, which is specifically designed for devices with Qualcomm Snapdragon X2 hardware and is not intended for most users. This version will not be available as an in-place update, will not have a successor (26H2), and will not support hotpatch updates. IT administrators are advised to use Windows 11 versions 24H2 and 25H2 for enterprise deployment. The release marks the retirement of the .NET Framework 3.5 as a Windows Feature on Demand optional component, effective with Windows 11 version 26H1. Support for .NET Framework 3.5 will end on January 9, 2029, prompting developers to prioritize migration efforts. Only devices with Snapdragon X2 hardware running Windows 11 26H1 will be affected by this change.
