Steven Sinofsky, former head of the Windows Division at Microsoft, discussed the company's engineering culture and its focus on resource management from 1980 to 2000, where every engineer was given a physical stopwatch to measure various performance metrics. This practice emphasized optimizing software for speed and efficiency, a stark contrast to modern applications that consume significant RAM due to shifts in market dynamics and hardware advancements. The current trend prioritizes rapid feature deployment over optimization, leading to performance issues in applications. Microsoft is responding to criticism by enhancing the performance of Windows 11, focusing on native desktop applications and optimizing core components, including the Start menu and File Explorer. They are also testing new CPU scheduling profiles to reduce micro-lags during user interactions.

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.

A cyber-espionage campaign is utilizing the XWorm Remote Access Trojan (RAT) to infiltrate systems via phishing emails and a Microsoft Office vulnerability (CVE-2018-0802). XWorm, first detected in 2022, allows attackers remote control over infected computers for surveillance and data theft. The campaign uses business-oriented phishing emails with malicious Excel attachments that exploit the vulnerability to execute a fileless attack. The malware connects to a command-and-control server, encrypting communications and transmitting system details. XWorm features a plugin architecture with over 50 modules for various malicious activities, including credential theft and DDoS attacks. Security experts highlight the ongoing risk of legacy software vulnerabilities and recommend patching outdated components.

Microsoft has officially ceased all support for Windows Server 2008 as of January 13, 2026, including paid extended security updates. This end-of-life scenario poses significant security risks for organizations still using the outdated operating system, making them vulnerable to cyberattacks. The transition away from Windows Server 2008 requires careful planning, as many organizations face challenges in migrating legacy applications to modern systems. The lack of ongoing patches means that any new vulnerabilities will remain unaddressed, potentially leading to data breaches and compliance failures, particularly in regulated sectors like healthcare and finance. Microsoft has encouraged migration to Azure, offering incentives for early adopters, but the transition can be complex and costly. The end of support also affects global supply chains and compatibility with newer software applications. Organizations are advised to conduct audits of their software portfolios and consider hybrid environments to enhance flexibility and security.

Microsoft's Smart App Control feature in Windows 11 is designed to evaluate and block potentially harmful applications by cross-referencing them against a database of known safe software. Initially, it required a clean installation to enable or disable, which hindered its adoption. Recent updates have removed this requirement, allowing users to toggle the feature on or off directly through the Windows Security app without a system reset. This change addresses user complaints and enhances usability, particularly for developers and IT professionals managing multiple devices. The feature employs artificial intelligence for real-time decisions on app safety and integrates with other Microsoft security tools. Feedback from the tech community has been positive, highlighting the update as a significant improvement in balancing security and user flexibility.

Microsoft has discontinued support for Windows 10, leading to around 500 million PCs being eligible for an upgrade to Windows 11, though many users remain on the unsupported platform. Zorin OS has gained approximately 780,000 users migrating from Windows within a month of this decision. Bazzite, a Linux-based gaming distribution, surpassed one petabyte of ISO downloads in a month, serving around 150,000 ISOs and attracting 730,000 visitors. Bazzite offers better hardware compatibility and pre-installed drivers for NVIDIA and AMD GPUs, making it a strong alternative to SteamOS. The improved compatibility of Windows games on Linux, aided by Valve's Proton, is contributing to the trend of users exploring alternatives to Windows.

Windows 10 reached the end of its support, prompting users to consider upgrading to Windows 11 or staying with their current operating system. Windows 7 has a market share of approximately 2.5%, and Windows XP holds 0.22%, translating to around 25 million machines running Windows 7 and 2.2 million on Windows XP. The primary reason users remain on these older systems is app compatibility, as many legacy applications do not run on newer operating systems. Upgrading involves significant costs and challenges, including data migration from legacy software. The decline in Windows 7 and XP usage is slow; in January 2023, Windows 7 had 9.55% market share, dropping to 3.05% by January 2024. Users often prioritize convenience and reliability, with many systems operating in isolation from the internet, reducing their vulnerability to threats.
