Microsoft is focusing on enhancing Windows 11 by addressing fundamental improvements, as highlighted by CEO Satya Nadella during the fiscal 2026 fourth-quarter earnings call. The company is investing in maintaining high quality and fundamentals for the operating system, with ongoing efforts to fix user concerns. Enhancements include testing a movable taskbar, reducing RAM consumption, fixing memory leaks, improving slow startup times, and updating File Explorer and Windows Search. The introduction of the Low Latency Profile update aims to improve responsiveness in the Start menu and shell. Microsoft has also removed the Copilot branding from certain applications to streamline the user experience. This renewed focus follows a challenging year with problematic updates, including a mandatory update in June that caused boot failures and other issues, prompting an emergency update in July. Financially, Microsoft's More Personal Computing revenue declined by 4%, with Windows OEM and Devices revenue dropping by 7%.
