Microsoft has confirmed it is testing Windows 11 version 26H1, a future update targeted at specific next-generation ARM-based silicon. The new version is reportedly being developed for upcoming chips like the Snapdragon X Elite 2 and potentially new Nvidia N1X processors. This signals a strategic focus on optimizing Windows for the evolving ARM architecture, which aims to deliver enhanced performance and power efficiency for future devices. The announcement is primarily of a technical nature, relevant to hardware partners and developers preparing for the next wave of ARM-powered PCs. As an early-stage development confirmation rather than a broad consumer release, it did not generate significant market reaction according to available information. The update underscores Microsoft's ongoing investment in diversifying the Windows ecosystem beyond traditional x86 processors.
