Marcus Ash, Corporate Vice President of Design and Research at Microsoft, discussed the stagnation in UI updates for Windows 11 tools like Control Panel, File Explorer, and Registry Editor, emphasizing the importance of maintaining functionality and compatibility with legacy systems. He noted that changing the Control Panel is challenging due to the need to avoid disrupting existing functionalities that users rely on. Microsoft is focused on modernizing these applications while ensuring core functionalities remain intact, using user behavior, telemetry data, and feedback to guide updates. Ash mentioned that the Registry Editor is also set for modernization without compromising its essential functions. Additionally, Pavan Davuluri, President of Windows and Devices, stated that Windows 11 would be optimized for devices with 8GB of RAM.

Microsoft released Patch Tuesday updates for Windows 11, specifically KB5094126 and KB5093998, along with dynamic updates KB5094149, KB5095971, and KB5094156. Two issues have been acknowledged: malfunctioning Office applications and complications with the Recycle Bin. In July 2025, Microsoft changed the default settings of Windows 11 to JScript9Legacy in versions 24H2 and later, continuing with version 25H2 in October 2025. This change aimed to enhance security by addressing vulnerabilities related to legacy scripting, particularly cross-site scripting (XSS). A support article details a compatibility issue arising from the transition from jscript9.dll to jscript9legacy.dll, which affects how JScript manages execution context. Functions and definitions established by one script are no longer accessible to subsequent scripts, leading to failures in legacy applications. To address this, Microsoft released the KB5077241 update, which requires manual activation of persistent JScript execution context through a Registry setting. The steps to implement this solution involve creating a feature control registry key and configuring a DWORD value for specific processes or all processes.

Microsoft is enhancing Windows 11 by reducing reliance on web-based components, which have caused performance issues. The user interface framework WinUI will now be referred to simply as "WinUI," indicating no plans for a WinUI 4, to reassure developers. Microsoft is integrating WinUI into the Windows 11 shell more rapidly, moving away from web components. A specialized team is focused on creating "100% native" Windows applications, starting with an overhaul of the Start menu from React Native to WinUI components. Performance, memory optimization, and quality control are top priorities for the WinUI team. A new system compositor is being introduced to improve UI performance, and enterprise-focused DataGrid and Charting controls are being added to WinUI. Microsoft is expanding open-source development for WinUI, allowing public testing and contributions. Migration support between WinForms and WinUI is being enhanced for legacy applications. An experimental project called Microsoft UI Reactor is introduced to simplify native application development using C#. This shift towards native development aims to improve performance and efficiency for all Windows users.

Microsoft will showcase a session at Build 2026 focused on porting x86 applications to Windows on Arm using AI agents. This initiative is in collaboration with NVIDIA, introducing the RTX Spark chip designed for Windows on Arm, which enhances performance for native Arm applications. Microsoft reports that 90% of user activity on Windows on Arm PCs involves natively compiled applications. The session will explore the use of agentic AI to assist developers in automating coding tasks and improving efficiency. A resource called "Works on WoA" helps users check application compatibility, while the Prism emulation layer allows access to a wide range of apps on Arm systems, though some legacy and specialized applications may face issues. The session, led by Qualcomm's Gaurav Goel, will provide tools for developers and is scheduled for June 3 at 6:20 PM ET.

Windows has a 99.9% compatibility rate with PC applications, making it the most compatible operating system compared to macOS and Linux. Windows is unlikely to become an atomic or immutable operating system due to its reliance on its current architecture and the challenges of modifying the Registry, which supports many legacy applications. Microsoft aims to create a versatile operating system with Windows 11, which will also be used in the upcoming Xbox console, but this approach may lead to inefficiencies. Alternatives like Bazzite, a streamlined Linux OS, are gaining popularity for gaming performance. Microsoft is addressing the issue of poor driver quality through its Driver Quality Initiative, which may make some legacy hardware incompatible. As competitors innovate, Windows risks stagnation if it does not make necessary changes.

Windows 7 was launched in 2009 and was known for its reliability and user-friendly interface. Windows 8, released in October 2012, marked a significant shift in Microsoft's approach by prioritizing touch control and eliminating the classic Start menu, which alienated desktop users. Windows 7 introduced features like Libraries and Windows Media Center, many of which were removed or obscured in later versions. Microsoft ended support for Windows 7 in January 2020. Windows 10, launched in July 2015, reintroduced the Start menu and offered a free upgrade for Windows 7 and 8.1 users. Windows 11 was launched on October 5, 2021, with stricter hardware requirements, including TPM 2.0, which excluded many existing PCs from upgrading. The evolution of Windows reflects a trend towards integrating Microsoft services and subscription models, diminishing user autonomy. Support for Windows 10 will end on October 14, 2025, pressuring users to transition to Windows 11 or consider alternatives.

Future and its syndication partners may earn a commission from purchases made through links in their articles. Recent reviews of the ASUS Zenbook A16 have raised discussions about Windows 11 on Arm, particularly regarding the performance of Qualcomm's Snapdragon X2 processors. Devices with Snapdragon X chips run Windows 11 on Arm, and Microsoft has improved compatibility significantly, with users spending 90% of their time on apps that run natively on Arm. While some reviews exaggerate app compatibility issues, many users cannot specify which apps do not work. The "Works on Windows on Arm" initiative lists compatible applications, including Google Chrome and Adobe Creative Suite. The ASUS Zenbook A16, featuring the Snapdragon X2 Elite Extreme and 48GB of RAM, now starts at ,699.99 after a price adjustment due to a listing error.

Google has mandated that all Wear OS applications must include a 64-bit version starting September 15, 2026. This requirement is part of a broader strategy that also applies to Android TV and Google TV, which will require 64-bit app versions from August 2026. Developers can still offer a 32-bit version alongside the new 64-bit applications, and the Play Store will continue to support legacy applications. A majority of Wear OS developers have already adopted the 64-bit architecture, although some dormant apps may present challenges. The transition to a 64-bit architecture is expected to enhance performance, security, and efficiency for chip manufacturers, as well as allow smartwatches to utilize more than 4GB of RAM.
