Microsoft rolls out a big Windows 11 Bluetooth upgrade, and AirPods now pair up to 15 seconds faster

The October 2026 update to Windows 11 introduces a Bluetooth enhancement that reduces connection times for AirPods by up to 15 seconds. This update also aims to improve Bluetooth reliability, with features such as accurate status reporting for connected devices, volume adjustments during calls triggering the volume flyout, and resolution of a bug that kept the Bluetooth radio active when toggled off. Improved microphone compatibility and enhanced audio quality are also expected. Users can check for the update by navigating to Settings > System > About, looking for build numbers 26300.9711, 26200.9711, or 26100.9711 or higher. The rollout may take several weeks for all users.

Microsoft Adds Incomplete Dark Mode to Some Legacy Windows 11 UI Elements

Microsoft has introduced dark mode support to Hyper-V Manager, a legacy application using the Win32 API. However, the implementation is incomplete, with several key components still displaying in light mode, including the main management view and the virtual machine listing. Features like the Hyper-V Quick Create Gallery and Virtual Machine Connection also remain in light mode, leading to a disjointed user experience. Microsoft plans to unify its user experience by transitioning to the desktop-only WinUI 3 framework to enhance application performance and achieve a cohesive UI across the system.

Missing Link: 30 Years of Windows NT 4

Windows NT 4.0 was released in August 1996, marking a significant shift in the PC industry from 16-bit DOS to 32-bit operating systems. It combined the stability of the NT architecture with the user-friendly interface of Windows 95, featuring a familiar Start menu and a robust 32-bit kernel. NT 4.0 was available in both workstation and server variants, allowing Microsoft to compete with UNIX workstations and Novell NetWare in the network operating system market. It laid the groundwork for future operating systems, including Windows 2000 and Windows XP, by enabling a unified management interface for servers and workstations. At the time, PCs typically had at least 8 MB of memory, and installation required booting from a floppy disk with files sourced from a CD.

ReactOS Runs Half-Life Natively: Open-Source Windows NT Clone Clears 3D Graphics Bar

ReactOS has successfully executed Valve's original Half-Life on consumer hardware, marking a significant milestone in open-source software development. This achievement was announced on June 10, 2026, after three decades of effort to reimplement Microsoft Windows. The game was run on a Dell OptiPlex desktop with an Intel Core i5 2400 processor and an NVIDIA GeForce 8400GS graphics card, demonstrating ReactOS's capability to handle real-time 3D applications without compatibility shims. ReactOS operates independently from Microsoft, sharing no code, and can execute a real-time 3D graphics workload natively. It has achieved approximately 90 percent GPU driver compatibility for Windows XP and Server 2003-era hardware through the implementation of the Kernel-Mode Driver Framework and Windows Display Driver Model subsystems. ReactOS is still in alpha stage, with limitations in application support and driver gaps for modern hardware. The project is working towards a new release, version 0.4.16, to enhance user experience.

Microsoft aims to speed Windows with ‘leap forward’ in WinUI 3 perf

Microsoft has announced a 25 percent improvement in the performance of WinUI 3, specifically in File Explorer components. There has been a 41 percent reduction in memory allocations and a 45 percent decrease in function calls. Some optimizations may involve breaking changes, which will initially be optional for developers. The enhancements are intended to become the default in future iterations of WinUI and the Windows App SDK. Despite these improvements, developers have expressed concerns about WinUI 3's performance, noting it is slower than WPF and UWP. The reliance on WinRT interop for component actions is seen as a significant factor hindering speed. Additionally, there are historical tensions regarding the adoption of Microsoft's frameworks within the Windows and Office teams, leading to skepticism about their reliability.

Microsoft CTO confesses that 30-year-old code from the mid-90s still forms the bedrock of Windows 11 — ancient Win32 API still the backbone, but CTO says it’s ‘more relevant than ever in 2026’

Mark Russinovich, the Chief Technical Officer of Microsoft Azure, revealed that Windows 11 relies on a significant amount of legacy code from the 1990s, particularly the Win32 framework. He acknowledged the challenges posed by this legacy software while noting its continued relevance as we approach 2026. Russinovich reflected on past attempts to update the Windows API, such as WinRT, which did not meet expectations. He also highlighted that Win32 has been crucial in developing tools like Sysmon and ZoomIt, created in 1996, which remain relevant in the context of Windows 11 and PowerToys.

Windows 11 still runs on code from the 1990s, Microsoft admits

Windows 11 relies on the Win32 API, a legacy system dating back to Windows 95, for core functionalities like right-clicking and launching applications. Microsoft’s Chief Technology Officer, Mark Russinovich, noted that the continued relevance of Win32 was unexpected, as few anticipated it would still be a primary interface in 2026. Despite attempts to modernize the Windows API with initiatives like WinRT, Win32 remains integral to many Windows operations. The separation between Win32 applications and web technologies has complicated the transition to a new API framework. Additionally, tools from Microsoft's past, such as Sysinternals, Sysmon, and ZoomIt, continue to play important roles in Windows management.
