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.

Rob Beard, product manager at Google, discussed Cameyo, a platform that allows users to access web applications and legacy software seamlessly. It enables IT administrators to deliver applications to users' devices quickly, enhancing efficiency and simplifying application management. Google has integrated Cameyo with Chrome Enterprise Premium to streamline the deployment and management of virtual applications, allowing access controls to be managed through the Google Admin Console. The integration also introduces security features like URL filtering and data loss prevention to protect sensitive information.

Windows 7 has been reduced to a size of 69 MB by a user known as @XenoPanther. This version is described as a "fun proof of concept" and can boot, but has significant limitations due to critical missing files, making it unable to run most applications. The project reflects a tradition among tech enthusiasts to minimize operating systems. Microsoft previously introduced a version of Windows Server called Nano Server with a disk footprint of 400 MB, later shifting to a base container image under 300 MB. Developers like NTDEV and the Tiny11 series have created slimmed-down versions of Windows 11. A 69 MB version of Windows 7 could still be useful for running legacy software without a full installation.

Microsoft will cease support for most versions of Windows 10 on October 14, 2025, while offering temporary Extended Security Updates (ESU) for version 22H2. Approximately 40% to 45% of Windows users globally still rely on Windows 10. The end of support raises cybersecurity concerns as Microsoft will stop issuing updates for vulnerabilities and bugs. Organizations using Windows 10 need to devise migration plans to Windows 11, but the transition can be costly and time-consuming, especially for those dependent on legacy software. Delaying migration poses risks such as regulatory violations, increased IT burdens, escalating ESU costs, and exposure to cyber threats. Organizations should prioritize migrating critical systems, review application support, and evaluate ongoing costs for legacy systems. Bitdefender offers security solutions for Windows 10 environments, including risk management, application control, cloud security, and monitoring services.

CVE-2025-59287 is a critical vulnerability in the Windows Server Update Service (WSUS) with a CVSSv3 score of 9.8, allowing for remote code execution (RCE) through deserialization of untrusted data. It is the first RCE vulnerability in WSUS and has been classified as ‘Exploitation More Likely’ by Microsoft. Organizations are urged to prioritize patching and reassess their WSUS server exposure to prevent attackers from deploying malicious updates. Additionally, two RCE vulnerabilities, CVE-2025-59227 and CVE-2025-59234, have been identified in Microsoft Office, which can be exploited through social engineering via the Preview Pane feature, allowing attackers to execute code without the target opening the document. Critical vulnerabilities have also been reported in the Agere modem driver, which has been part of Windows operating systems for nearly two decades, highlighting issues with legacy software in cybersecurity.

On August 24, 2025, the 30th anniversary of Windows 95 was marked. Windows 95 was Microsoft’s first mass-market 32-bit consumer operating system, which sold one million copies in the first four days and approximately 40 million within a year. It aimed to unify MS-DOS and Windows into a single user experience with low minimum requirements: a 386DX processor, 4 MB of RAM, and 50-55 MB of disk space. Key innovations included the Start button, a unified interface, a full 32-bit Win32 API, and multitasking support for software from three generations. Official support for Windows 95 ended in December 2001, but its influence persists in modern operating systems. The launch featured the Rolling Stones’ song “Start Me Up,” which became iconic in tech marketing, despite initial challenges in securing the rights. The advertising campaign included celebrity appearances and contributed to Windows 95's cultural phenomenon status.

Windows 95 is still in use on a farm near Düsseldorf, Germany, where it operates an egg sorting machine that processes 40,000 eggs daily. The machine, which measures approximately 40 by 40 meters, sorts eggs by size, weight, and origin, packing them into boxes for distribution. The software logs sorting results, and a compatible Brother printer handles printouts. The original programmer is no longer available, making updates impossible. Despite potential challenges, the farmer, Peter Huber, does not plan to purchase a new machine due to high costs and limited additional functionality. Windows 95 recently celebrated its 30-year anniversary on August 24th.
